Superhub : Superhub & Portforwarding ?

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.

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?

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"

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.

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.

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.

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.

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.

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 ?

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.
