Re: Business Service with 13 Public IP Addresses

Glad I found this thread - I have been going round and round in circles with this for months on and off.

I've got 5 (usable) IP's with my setup, and HITRON currently in modem mode. I can access the Hitron admin screen directly using the first IP in my allocated range, and the modem behind it (LinkSys EA9500) using the 2nd, but can't get any of the remaining IP's configured.

If I take the HITRON _out_ of modem mode, do I still essentially connect LAN1 from HITRON into the EA9500 and run wifi etc through that?

Still not clear to me how I manage the static IP's as I can't use port forwarding if multiple devices / servers will all be using HTTPS/443

Am I thinking this the wrong way, or do I need a different router (Draytek?) behind the HITRON.

Waaaaaaay more difficult than the enterprise networking kit I work with!

Re: Business Service with 13 Public IP Addresses

I have a similar setup. First thing to do for this to work correctly is to take the Hitron OUT of modem mode. Surprised you can even get it into modem mode when configured for fixed IP addressing, as that should remove the option.

Secondly - check under Admin - VMB IP service at the bottom of the screen that the GRE tunnel status shows CONNECTED.

After that connect your router to any of the LAN ports on the Hitron and configure it to use a static WAN IP address and use the next useable IP address from your IP block. Make sure the subnet mask matches your IP block size. on your LAN side use a range such as 192.168.1.0/24 and ensure your external router is configured to perform NAT, as the Hitron will not do that in this config. Also you will need to define the next hop address on your router to point to the Hitron's IP address - first one in your IP address block.

To use other IP addresses in your fixed IP block you have two options - connect other devices to the Hitron and configure them with other IP addresses in your fixed IP block. OR ensure you use a router behind the Hitron that can use multiple IP addresses on it's WAN port. I am not familiar with the EA9500 so not sure if that router can do it. Draytek routers definitely can and Cisco IOS based routers definitely can. I use a Draytek 2960 in this config with no problems at all. Draytek uses the term IP alias and Cisco IOS routers would use secondary interface addresses.

Give this a try and let us know how it goes - will help more if you need it.

Away from home for the next couple of days but will give this a go over the long weekend. Many thanks :)

Re: Business Service with 13 Public IP Addresses

Have they fixed the performance issues with the Static IP service?

Does the GRE tunnel have issues either connecting to an external VPN service from inside the network.

Does the GRE tunnel have issues with you running your own VPN service (openvpn or L2TP/IPSec)?

I’m considering the 13 IP service and want to make sure they’re are no issues around this.

Thanks

Re: Business Service with 13 Public IP Addresses

Yes perforamcne issues with the static IP service was resolved a fair time ago... as an example - speed test I've just carried out:

https://www.cableforum.uk/images/local/2019/08/2.png

I regularly use work VPN services via the GRE tunnel with no issues. This is connecting to both Cisco & Juniper VPN services. I have the 5 static IP address service.

Cheers, following your post I bit the bullet. I’ve just set it up after receiving the IP details earlier this evening.

As expected, L2TP IPSEC VPN server doesn’t work (I assume some GRE conflict), but outgoing connections to the external LT2P IPSEC servers work.

No biggie as I have OpenVPN on my network here, so I will use that going forward.

Took me a while to figure out that when the modem reprovisioned it stayed in modem mode rather than switching to router mode, but once I switched it back to router mode the GRE tunnel came up and the internet was working on my first static IP.

Thanks for your reply!

Re: Business Service with 13 Public IP Addresses

Spoke too soon.....

I have issues playing media from home now, it just constantly buffers, before i switched to the static IP service it worked flawlessly, now its unusable.

Re: Business Service with 13 Public IP Addresses

I’m not sure if something else is at play here, if I put the hitron back into modem mode I get the same IP I had previously on the dynamic service, so I assume it’s working exactly the same as it did before, is this a correct assumption?

If so, then something else has happened as streaming from my house behaves the same on the dynamic up as it does when it’s in router mode with the GRE tunnel enabled and a static IP assigned.

Re: Business Service with 13 Public IP Addresses

I've experienced no issues with streaming, so don't think that is related to the static IP service - which I think you've confirmed when using a dynamic address.

Suspect the cause of that is something else.

My unraid server has a 10G fibre connection, I have a 10G switch as the backbone of my network, when I was playing with getting the connection to max out iperf3 across my LAN I set the MTU to 9000, but never set it back to a sane value.

It seems this was the culprit, creating lots of fragmentation of packets when the WAN became involved, especially with the GRE encapsulation. I’d noticed that unless I carefully selected a Speedtest.net server I got results much lower than I expected, I have changed the MTU on the unraid server down to a better value (although not yet optimum) and I was able to stream from a web browser on my phone without buffering. Running a Speedtest on a VM on unraid now showed decent results on a random server as well.

Need to do a little more testing, by pretty sure I’ve discovered my issue.

Thanks for your responses again.

Re: Business Service with 13 Public IP Addresses

Again, seems to be a placebo effect.

I'm really struggling here as to what the problem is, I'm back in modem mode with my dynamic IP and it just won't stream properly now.

The fact that it no longer works in dynamic ip mode seems to imply something else changed, but no configuration changed on the server or gateway barring manually setting the static IP or DHCP for dynamic mode.

The residential service status checker shows no issues for broadband in my area.

I'm clearly overlooking something, but for the life of me I cannot see it.

Re: Business Service with 13 Public IP Addresses

ok, something very weird is happening.

i ran an iperf3 server on same host and forwarded the ports.

running in reverse mode from my office:

Code:

Abysmal single thread performance, so i tried 2 parallel and the connection maxed out.

Went back to single thread again and now see this:

Setting the bandwidth option results in a consistent maxed out upload.

Re: Business Service with 13 Public IP Addresses

My local utilisation must have increased randomly with me switching to static IP’s.

I’ve been running tests on and off all day and the upload has been fine, just ran one now (peak time) and bang it’s not very good at all.

Re: Business Service with 13 Public IP Addresses

Is anybody able to run an iperf3 server on another machine and perform tests from their static IP service to it?

I'm running a server and using the following iperf3 command to test:

Am I overthinking this?

I have an assigned range from Virgin: Start: 80.nnn.nnn.24 / End 80.nnn.nnn.31
First USABLE IP auto assigned (?) to the Hitron is 80.nnn.nnn.25

In my modem mode I have managed to get a fixed IP Address on the LinkSys as 80.nnn.nnn.26 coning from LAN1 into WAN port.

Rather than trying to figure out how to configure multiple WAN IP's within LinkSys, and seeing as I have to have the HITRON powered on and active, am I better off taking it out of modem mode, leaving LAN1 connected to WAN but then using LAN2, LAN3 and LAN4 to handle three other fixed IP addresses to e.g. Web / File / LDAP ?

All LAN activity and wireless would be handled via the LinkSys so no need to add or change this part of the network?

Assume I would have to take the HITRON out of DHCP mode and manage the fixed IP routing there, but think this may be preferable.

Thoughts?
