Superhub & Portforwarding ?
 

my superhub is currently in modem mode, running a Linksys router,
But am thinking of putting it back to router,
Does anyone know if you can configure port forwarding on the superhub and setup DDNS ?

Re: Superhub & Portforwarding ?
 

If you search the term "dyndns" here: http://www.alex-brown.co.uk/2010/11/superhub.html

You'll see that the voice of VM has said that DDNS is not supported on the SH.

It can only be a regressive step (from the network perspective) if you ditch modem mode. I'm sure others will say likewise.

Re: Superhub & Portforwarding ?
 

Yes you can port forward. DDNS is not supported internally, DHCP is all you need unless you really need named addresses internally? For being able to access your router via a URL across the internet, then no, currently there is no facility for the Superhub to update an external service with your IP intermittently. It would be a great idea though. You can either get another router that supports it e.g. Draytek. Or else get a small device with the feature e.g. cheap webcam, but you will have to leave it plugged in constantly. That said your IP will rarely change so just try writing it down somewhere e.g. on your phone.

Re: Superhub & Portforwarding ?
 

I have two other routers, was thinking of putting the superhub back in router to use the ethernet ports as the Superhub is next two my printers and NAS, and using the other two routers and a AP in bridge mode in roofspace to max out wifi at home, wanting to try DDNS to use a iphone app to access home network and cloud storage, just starting out with all this, want to know more.
Think i may need named addresses internally.

Sorry, could not find "dyndns" on that link,
Would Virgin support DDNS if Superhub is in modem, and using my Cisco router?

Re: Superhub & Portforwarding ?
 

Well, you took my word for it anyway. A third party router that supports DDNS is not hindered by the SH in modem mode.

BTW the link and search did work for me. The search would have brought you:

Hi

Thanks for the comments - sorry to have been a few days in approving comments & responding ... been maxed out!

Andrew - This is a new one on me. Can you please report it on the Help & Support forums (http://community.virginmedia.com/) with some details and the community team will pick it up asap.

Mr Barton - Don't have a firm date yet, but it's being worked on right now and we'll publish details on the Help & Support forums as soon as we have some news (as per previous responses).

John - Way over my head sorry, but I checked in with the expert:

"Your Synology NAS box should work fine with our SuperHub but may require a little bit of port forwarding and configuration for it. Does your current router support Dyndns login via its configuration pages? Our Hub doesn't directly support the Dyndns login so it would just be a case of checking every now and then to ensure your IP hasn't been changed and updating your Dyndns account accordingly if it has. Other then that just setup the required ports to forward and it should work fine :)"

Re: Superhub & Portforwarding ?
 

DDNS isn't that neccessary with VM's semi-static IPs anyway, so having a client running on your PC tends to be enough. Over the last 6 years my VM IP has only changed 10 times.

Re: Superhub & Portforwarding ?
 

I have been on the same IP for at least the last 6 months.

Re: Superhub & Portforwarding ?
 

Think mine has been the same since i've been noticing it

Will Virgin reserve an IP address, or is it chargeable ?

---------- Post added at 15:12 ---------- Previous post was at 14:08 ----------

Thanks for that Seph, you've answered a question, what i'm trying to achive is

1, a better understanding of routers & bridging them, networking, wifi, etc

2, I'm trying to get a iphone app i have working on 3G, which can access my whole network called FileBrowser, its fine at home on wifi, i have a Cisco EA6500 router as router at mo, its a newish model, recent F/W updates seem to upset its cloud based configuration page, which seems to be affected when you update F/W, it has no local alternate config page (yet), i'd like to get that and similar working with just my IP address if poss.

Re: Superhub & Portforwarding ?
 

why why oh why? Why don't you use your Linksys router and your primary router with dhcp and disable dhcp and wireless on the shub and use it as a switch for your printer and whatever else?

Re: Superhub & Portforwarding ?
 

General, Sir, why, why, why haven't i tried that ?

Because i've just read your post, which sounds brilliant, just what i want, i think as a bit of a noob, disabling DHCP and wireless on the Superhub should just invole ticking or unticking a box, not sure how to use my primary router, a Linksys EA6500 and a Linksys E4200 V1 which is cable bridged and a Edimax Wireless Repeater which is also cable bridged from The EA6500, with DCHP?
also hoping to add a TP Link TL-WR1043ND with dd-wrt f/w in bridge, or repeater bridge in dd-wrt terms.

How do i, simply, use the routers with DCHP ?

Re: Superhub & Portforwarding ?
 

you only need to let one router handle the proper "routing" side of things and that should be the high end linksys router. It can do all your dhcp, you can setup some reserved static ips for your other routers and hardware (dhcp reservation list button), port forwardings and your ddns stuff. It is perfect for it. On the other hand you want to tax the shub as little as possible then you don't have to worry about anything going wrong. Having weak links in your network isn't good.

It should litterally be a check box job and you can untick dhcp on any routers (inc shub) you are going to distribute around the house. This means that all your internal ip addresses will be handed out by your core router (the 6500). I would keep wireless switched on on the 4200 and put it at the opposite end of the house. Set the same ssid on both routers and use different channels and that way your have got 2 kick ass routers giving your full strong wireless coverage. You can use the shub whereever you want as a switch with dhcp, wireless, and FIREWALL disabled.

Also, one of the many joys of having a Linksys router is that you can set your dns servers. I have been using google dns servers (8.8.8.8 and 8.8.4.4) for years and they are great. When there are issues with VMs dns servers and you get other users on the forum moaning they can't get to certain sites (all the shub users :) ) you can sit back with a big grin on your face.

Re: Superhub & Portforwarding ?
 

Unfortunately the solution proposed by GM won't actually work...

I'm not entirely clear what you're trying to achieve, but a few pointers:

1. You should ideally only have one unit providing routing functionality in your network.
2. If you need to use the ethernet ports on your SH, then the SH has to be in router mode and therefore 'the' router. Modem mode disables the switch functionality of the SH.
3. Other routers can be used as wireless access points by turning of their DHCP server, giving them a management address outside the main router DHCP scope (but in the same subnet) and connecting one of the LAN ports on the access point 'router' to the main router.
4. The SH does not support DDNS so one of your other routers will need to be the main router if you need this. The SH will then need to be in modem mode (See 2) Alternatively you could run a DDNS update client on one of your PCs.
5. I would recommend putting all access points on the same SSID and the same channel for 'seamless' roaming around the house.
6. I'm not familiar with the iPhone app you want to use. Do you only need to connect to one of your internal machines from the phone when outside? If so then you'll need to sort out the port forwarding in the router to that machine.

Re: Superhub & Portforwarding ?
 

It will, it's just not ideal. Then again having a Superhub in your network is not ideal.

Port forwarding and DDNS

NAT, yes. Routing, no. Multiple routers is fine, that's how the whole internet works.

Don't need to be anywhere near the same subnet.

No they dont and no it doesn't.

Or you could run a DDNS update client on a second router, like was already suggested

Re: Superhub & Portforwarding ?
 

Always thought the primary router should be the first thing after the modem,
But the router, think I'm understanding more of what that means, routes all the internal IP address to stuff ?

The shub is next to the cable access point at one end of the single storey bungalow, next to two printers, NAS and stuff, with a cable into roof space serving EA6500 as router, with a E4200 in cabled bridge plus a Edimax Repeater also in cabled bridge from my EA6500, plus TiVo, printers, NAS n stuff cabled from EA6500 assisted by a 5 port switch, using unused ports on shub will be an advantage,
If I know what to do, using shub with stuff switched off, can be tried, if it doesn't work out,
I can try another configuration ?

Re: Superhub & Portforwarding ?
 

Your plan is sound. The main thing is to give the SH the minimum amount to do by turning off wireless & firewall. This leaves it mereley to route out to its four switch ports.

You'll want to allow for double natting if your devices are sensistive to this; you'll need to set each router into bridge mode with own discrete DHCP range for serving out to their attached devices. Double natting takes care of addressing from the SH to the appropriate router.

There is no reason I can think of why the solution you propose shouldn't work with stability.

Re: Superhub & Portforwarding ?
 

If all the routers (other than the SH) are in bridge mode this will work (assuming the DHCP servers only serve to their LAN side connections when in bridge mode?) but with the following caveats:

1. DDNS updating may well not work as the router given the task of running the update will have a private IP address on its WAN port, not the VM public address.
2. Machine IP addresses will change as you move between segments.

Far easier, IMHO, to simply use the downstream routers as access points...

EDIT

Looking at a Cisco document, their implementation of 'bridge' mode completely disables all router functionality, including DHCP, and turns the unit into an access point anyway...

---------- Post added at 12:57 ---------- Previous post was at 12:28 ----------


Accessing the printers and the NAS that are connected to the SH from the LAN side of the downstream router will be problematic and speed limited! 'Discovery' software won't work for printer installation (if required). Static IPs will need to be configured on the SH connected devices (not necessarily a bad thing of course!) and this isn't mentioned by GM...

"Not ideal" is a bit of understatement! It's a dog's dinner :)


The routers under discussion are, by default, NAT devices.


Makes management of them a bit more awkward if they're not? No reason not to be on the same subnet so why make life difficult?


The WAN address of the second router will be the private address allocated by the SH so that's likely to be the address used for DDNS update. PC clients are 'NAT aware' and will identify the public address when behind a NAT router but do router clients work in the same way? I haven't tested this (have you?) but it would seem unlikely...

Re: Superhub & Portforwarding ?
 

Yes it will. The only booboo i made suggesting you put the shub in modem mode and then use it as a switch. I'll correct myself: as we dont want to use the shub as either a router or wireless ap ditch it all together and get a gigabit switch

Re: Superhub & Portforwarding ?
 

Ah, the missing link! You didn't mention modem mode so you'll forgive the innocent reader for assuming you were (as was the OP) talking about router mode. All your advice to turn off SH DHCP and wireless (which you can only do in router mode) duly ignored :)

Re: Superhub & Portforwarding ?
 

Seph, get your first paragraph, Shub's don't have a good reputation, the extra ports could free up my five port switch,

Agree with your second paragraph, but....

Double Natting ??

Networking just gets harder !

Could anyone point towards a idiot guide for me pls ?

Re: Superhub & Portforwarding ?
 

Correction to my own post - Accessing the printers and NAS won't work...

To the OP:

If using the SH ethernet ports is important then you'll have to use it as a router and my advice in post 12 stands. However if these ports don't need to be used then continue using the E6500 as your router (SH in modem mode) and use the other routers as access points. I'm confused at this point though as isn't that what you're doing anyway?

Back to the iPhone issue - If you want to be able to access machines (plural) on your LAN you're into the realms of setting up a VPN server in your LAN (and client on the iPhone) rather than port forwarding...

Re: Superhub & Portforwarding ?
 

It'll work just fine. Before people had DDNS clients in their routers they were running on PCs with private IP addresses. The update server sees the public IP as the source of the connection whenever the client tries to update anyway.



Not necessarily. I don't see why they would. You would only have one subnet and one IP range.

Easier, if you don't need to magic up an extra 4 ports and additional cable out of thin air...

That's basically what an AP is... a bridge.

I don't see why it would. It should go at full switch speed, i.e. gigabit.

Should work just fine. When set up correctly you will still only have one subnet and one ethernet domain.

Should work just fine without. The second router dishing out DHCP addresses will dish out DHCP addresses.

Again, the majority of corporate LANs and the internet at large works on this sort of setup, it's not ideal only in it's hard to set up properly.

Unless you turn NAT off. NAT is an optional feature and present on just about any router.

I don't get your point. My proposal *is* to put them all on the same subnet.

Or, it'll use the public address like it should do.

Yes.

Yes.

Works just fine. On Openwrt especially, you can set it to use any IP and fetch it via any mechanism. Either the server can use the IP it sees the connection coming from, or the router can go to www.whatismyip.com and submit the IP it gets from there.

---------- Post added at 17:14 ---------- Previous post was at 17:13 ----------

The problem would be, obviously, you would need an extra switch and an extra cable running across the house. Which can be avoided with some clever setup.

---------- Post added at 17:17 ---------- Previous post was at 17:14 ----------

Should work just fine. You will still have one continuous ethernet broadcast domain.

Probably the easiest option tbh.

Not sure why you would need a VPN. Port forwarding works in all circumstances and most mobile clients use it as their primary/default access mechanism.

Re: Superhub & Portforwarding ?
 

You'd have saved a lot of typing if you'd re-read the posts I was replying to again rather than posting out of context one liners...

Re: Superhub & Portforwarding ?
 

Except this forum strips quotes from quotes...

Re: Superhub & Portforwarding ?
 

For the benefit of the OP, there are a number of key concepts that need to be understood.

1. Ethernet Switching
2. IP Routing
3. Network Address Translation
4. Dynamic Host Configuration
5. Name Resolution

All of these are required in your setup to enable the devices you have on your home network to communicate with each other and with the wider Internet.

The physical devices you have may include more than one of these functions.

e.g The SHub includes IP routing, Ethernet switching, NAT and DHCP in router mode.

I suggest you think simple when setting up you home network. Don't use multiple subnets and use static IP addresses for devices that provide 'server' functionality.

You should only have one device with router and NAT functionality that provides the interface between your local subnet and the Internet.

If real speed is required on intenal links use one core ethernet switch with multiple intefaces and avoid uplinks between switches.

Re: Superhub & Portforwarding ?
 

OK chaps, thanks for all this lively discussion, but this OP is a bit of a noob, who is getting a little confused (??)

So we're all agreed, you cannot successfully put the shub in router mode and disable the other stuff, AND have another router next downline on the same network doing all the router stuff,

What does everyone think is the best solution, after this discussion ?

Re: Superhub & Portforwarding ?
 

As I've said before, all hangs on whether you *need* to use the SH LAN ports for your printer and NAS?

Best to use the SH in modem mode, the E6500 as your router and the other routers as access points (bridge mode or connected LAN to LAN) at various points around your house but then you can't connect the printer and NAS to the SH...

This still doesn't address your iPhone app but you haven't really described what you're trying to do with it.

Re: Superhub & Portforwarding ?
 

Yep - Modem Mode. The principal advantage is that you'll be free of the SH's crapismos, both present and future with rock solid behaviour.

Then have access points as the Ferret says.

Re: Superhub & Portforwarding ?
 

No I quite clearly said you can, and that's how the whole internet works.

If you need the ports on the Superhub, use them. If you can get a second switch and cable and run it from your own router back to the Superhub then even better.

Re: Superhub & Portforwarding ?
 

Hi Guys,
Hope everyone had a good christmas,
Ok, story so far, in my original post i was trying to find out about port forwarding and DDNS to try to access my home network remotely with my iPhone 5.

The only remote app i've got working ok is the Synology native app into my DS212j NAS box, n that's not brilliant, compared to a Cloud app like Dropbox which connects nearly instantly on a good 3G signal.

Put the shub back into router this morning to get Virgin to check out the speed we are getting, if your using another router, they will not help untill the shub is modem, we use most stuff on wireless, three laptops & four iPhones, not been showing good speeds on the speedtest app on my iPhone, Virgin said, try the laptop wired, 62mbps !

So that's sorted, left shub in router, and switched EA6500 back on, also still in router, works OK, trying on both laptop and iPhone,

Next trusty old Cisco E4200 V1 in wired bridge mode back, tested, OK,
one little prob there, connects ok on 2.4ghz but not 5GHZ, is 5ghz disabled in bridge mode ?

Next, Edimax repeater in wired bridge mode, fine.

It all seems stable at mo, will give it time n see how it goes, then prob start switching stuff off on shub n see how that goes.

What i'm thinking now is, Cisco EA6500 is a new router, with not the usual local accessed router page, but it uses CiscoCloudConnect which you need a working internet connection, with no local backup option, which is abit bad really if your internet connection goes down,
People have had a few probs with this service, usually after firmware updates, which have been about two or three, check out this post -
http://homecommunity.cisco.com/t5/Wi...542800/page/29

If my system maintains stability, i may put the E4200 back into router, put the EA6500 into bridge whilst Cisco are maturing the firmware, to use for a good wifi signal in the lounge where we access the internet alot, it'll look ok next to the Tv because of its low, no external aerial design, we already have a ethernet cable into the TiVo box, so i'll plug the EA6500 into that, shorter cable into TiVo, so it'll give two ethernet ports plus two USB ports easily accessible.
I don't desperately need the shub's LAN ports, but if the shub can be used like this to an advantage, thats ok with me,
hope you guys stick around on this, just in case something goes wrong ?

Whilst on the chat to Virgin, they tried to sell me their Security Software n tech help service for £10 a month, is it any good ?

Re: Superhub & Portforwarding ?
 

Not sure why you've left the SH in router mode? It's been explained that you only need to do this if you must use the SH LAN ports. If you don't *need* to use them then modem mode is a much better solution...

Re: Superhub & Portforwarding ?
 

Well, if i can use them in router mode without causing problems, that's a good thing, BTW, Virgin 120mb to plusnet ? what speed is that ?

Re: Superhub & Portforwarding ?
 

I read through this hoping that someone could give some tips on port forwarding but cannot find the answer I was searching for so I would be grateful for any advice on how to set port forwarding/port triggring on the super hub.

Basically my problem began when VM customer services advised me to use the SHUB exclusively for both my ethernet and wireless connections after me reporting that after upgrading to 100MB from 50MB my speed increase had only increase to 57MB.

I was using the SHUB in modem mode only and used my Linksys router for wireless, ethernet and was able to view the images from my AVTECH CCTV system on the local network computers. Although I was reluctant to use the SHUB in full router mode after reading adverse comments on here as to it's shortcomings I gave it a go as my Linksys router, although performing faultlessly was only 10/100 spec and with the 120MB upgrade coming I knew I would never get full speed from it.

Actually, I was quite pleased with the results, even the wireless signal was quite strong but the problem I have is that I am now not able to view images from my security cameras via the ethernet connected AVTECH 4CH MPEG 4 DVR system any more.

I have tried everything that I can to open Port 80 on the SHUB but to no avail and would really appreciate any assistance anyone may be able to offer.

If it is possible I would prefer to carry on using the SHUB but if not then I guess I shall need to upgrade to gigabyte router and go back to using the SHUB in modem mode.

p.s. Even after ditching the Linksys the speed increase was minimal, peking at 64MB. :td:

Re: Superhub & Portforwarding ?
 

Eh? Port Forwarding exists, and works nicely.

Log in @ 192.168.0.1, enter your admin username and admin password, click Sign In
Click on the Advanced button near the bottom
Scroll down the screen to "Security"
Click on "Port Forwarding"
Enter your port forwarding details.
Click on Add Rule
then finally click on Apply

Re: Superhub & Portforwarding ?
 

I was in the same position dude but I did the right thing and bought a new Linksys router pre-upgrade and I was adament that I wasn't going to use the shub. I would advise you to do the same.

Re: Superhub & Portforwarding ?
 

Just stick to modem mode and upgrade your router. Trouble free internet = modem mode. You'll have nothing but problems (as you've seen) with router mode.

Shops are open today!

Re: Superhub & Portforwarding ?
 

Just to be clear - Your DVR is on your local LAN and you can't see it from computers also on your local LAN?

If so then this is nothing to do with port forwarding - This feature would allow you to see the DVR from elesewhere on the Internet i.e. outside your LAN.

If your DVR automatically configures its IP address (via DHCP) the the change to the SH will require you to reboot the DVR (to pick up a new address) and then you'll need to look through its menus to find the address its been given.

If you manually configure the address, you may need to reconfigure it so the address is in the same range as the computers.

What address is it on currently?

Re: Superhub & Portforwarding ?
 

Hi, thanks for the reply, the attachments below show the log on screen and address info that worked flawlessly with the Linksys, all that has changed is the router. I assumed that it was due to port forwarding as Port 80 is showing as closed when checking it out via the "check open port tool"

Attachment 24095

Attachment 24096

Attachment 24097

Any help as to a remedy would be welcome otherwise, as suggested, I will need to get another router that will allow me to connect to my CCTV system.

Also apologies if any of the info shown on the CCTV configuration needs to be blacked out for security reasons but I assume that as I can't get access then no-one else can either, lol.

Re: Superhub & Portforwarding ?
 

As suspected - The IP addresses that your Linksys router used was in in the range 192.168.1.xxx but the SH, I believe, uses addresses in the range 192.168.0.xxx The Linksys router was also on 192.168.1.65 which is why the DVR has this specified as the Gateway.

Reconfigure the DVR to be something like:

IP address: 192.168.0.100
Subnet Mask: 255.255.255.0
Gateway: 192.168.0.1
DNS Server: 192.168.0.1

The example above assumes that the SH is 192.168.0.1 and that the address 192.168.0.100 is outside the range of the SH DHCP server (Mine's in modem mode so I can't check)

This should restore connectivity from your local machines.

Port forwarding in the SH only needs to be setup if you want to access the DVR from elsewhere on the Internet.

Re: Superhub & Portforwarding ?
 

Thank you so much, both for the fast response and the very knowledgeable deductive process you used to reason out my problems. The DNS server address kept reverting back to 168.95.1.1 but after saving the other settings everything is working as before. Hope you have a great New Year. :nworthy:

Re: Superhub & Portforwarding ?
 

grimwau,
they are quite good here, my shub is now back in modem, using a Cisco router, seems very stable, shub wireless range is crap anyway,
Virgin want you to use the shub in router all the time, if you contact them with a tech enquiry and find out you have it modem only, they'll not usually help you till its back in router mode.

Re: Superhub & Portforwarding ?
 

That was exactly the way my discussion went.

I was told to disconnect the Linksys and use the SHUB in router mode before I would get my 100MB. Actual speed increase was in single figures and that could possibly just be due to the BB speedtester used and the amount of internet traffic.

Re: Superhub & Portforwarding ?
 

Agree about the speed, it can vary, sometimes more than single figures, if you test at speedtest.net, you can change servers, which, some servers give you a faster speed, not necessarily the nearest sever.

Be nice if you could get your internet connection to stay on a server you choose for its speed ?

Re: Superhub & Portforwarding ?
 

I stopped using speedtest.net some months ago because results cannot be trusted.

I use Jack Dinn's JDAST multi-threaded program, runs on your PC, also reports jitter in a nice graphical format as well as CSV for processing in Excel.
