How to access Vigor 120 (Modem) was created by westyfield2
My setup is probably familiar to you guys given that this is a DrayTek forum, but I thought I'd include a diagram incase of need :).



I'm on O2 ADSL2+ LLU (G.992.5 annex A) with a Dynamic IP, and set up Vigor 120 as per the guide online . It's plugged into a Vigor 2920n Router, which is set to Dynamic IP. It all works fine 8).

Vigor 120 IP: 192.168.2.1 (its default)
Vigor 2920n IP: 192.168.1.1 (its default)
PC IP: 192.168.1.*** (DHCP)

However to access the Vigor 120 (mainly to check the line stats) it's a bit of a faff. I have to unplug the 120 from the 2920n (thus removing that WAN link from use) and plug it directly into a PC (thus removing the PC from using the network). Then I set the PC to a static IP of 192.168.2.11 rather than using DHCP, otherwise it ends up being DHCP'd my public IP.
Then I can browse to 192.168.1.1 and use the GUI menus or telnet into it and get the line stats.
Whilst I'm checking the line stats no-one use the line, as the 120 isn't connected to the 2920n for others to use it and my PC can only use the line if I let the 120 give it the public IP address (but then the PC can't get to the 120).

This is obviously less than ideal, but admittedly works.

Is there anything I can do make this less of a faff? Ideally I'd want either to telnet straight into the 120 from a regular LAN PC whilst others are still using the 120's internet link, or a way of the 2920n showing the Sync Speed/Attenuation/SNR in it's GUI.


Any suggestions and ideas appreciated :). I genuinely don't have a clue how, or even if, it's possible!

Cheers,

I'm on O2 and configured my Vigor 120 to use MPoA Bridged, gave the Vigor 120 a LAN address of 192.168.0.254 and connected it to a LAN port on my Linksys WRT610n (on range 192.168.0.x), then connected a patch cable from another WRT610n LAN port to the WRT610n WAN port. Configured the WAN interface on the WRT610n with my O2 static IP address settings.

Now I can access the Vigor on address 192.168.0.254, my WRT610n on 192.168.0.1 and all my other devices are somewhere in between. :)

The only downside is you lose two LAN ports (and need a second small patch cable).

I run a WRT54GS (with Tomato 1.28) and a Vigor 120 on Tiscali/TalkTalk.

In order to access the Vigor's web interface and telnet, I set up a static route on my router.

Code:
Destination: 192.168.2.0 Gateway: * Subnet Mask: 255.255.255.0 Metric: 0 Interface: vlan1 (WAN)

For the destination, if you've changed the subnet, put your own, but just make sure your internal network is on a different subnet or you'll have issues.

I'm not sure of the procedure to do this on a Draytek router, but I'm sure it's quite similar.

Fit a switch/hub between the 120 and your router and plug your PC into the switc/hub using a fixed IP addres 192.168.2.## unless you have changeed the 120's default.
enter 192.168.2.1 into your browser and you are in

Thank's for that Cam, looks intriguing!

I haven't changed any of the IPs/Subnets from default so in theory all I'd need to change is the Destination IP from your 192.168.2.0 to my 192.168.2.1 (any reason you change the Vigor 120's IP from default BTW?)

Now to find how to do this static route on the Draytek router...

Just found this thread whilst searching for a solution to this problem, I'm trying to setup the 120 on a v2930 but I can't seem to get the static route working so I can access the 120's interface, I think the problem is I need to enter a Gateway in the settings for the route but I'm unsure what it should be in this setup.

Can anyone help please?
