My Draytek Vigor ADSL modem is setup in bridge mode on 192.168.2.1 and my WNDR3700 wireless router is on the standard 192.168.1.1 with DHCP enabled etc. Everything is working fine, except I can't see the ADSL modem from within my LAN.

Previously with my WRT54GL I was able to 'see' the Vigor but I was using the Tomato firmware with some funny scripts to setup the necessary routes etc.

Can anyone tell me how to do this on the stock Netgear firmware? I am guessing it is some sort of static route, but nothing I have tried has worked so far. Or do I have to load the DD-WRT firmware in order to set this sort of thing up?

Hoping someone on here has the networking nous for this...

Does the lack of replies mean this is not possible with the stock Netgear firmware?

Should be possible to add a static route so the Netgear knows it can get to the modem ip address out the WAN interface, not familiar with the Netgear admin ui though so can't give you specific advice.

Thanks - but I am not sure what to enter for the WAN IP address - since as far as the Netgear config goes, the modem is effectively transparent - all I see in the config screens is the dynamic IP address assigned by Telecom - which will change over time.

The modem IP address is 192.168.2.1 and the Netgear is on the standard 192.168.1.1.

Below are the instructions on the router config page, hoping they might give you an idea of what I need to set this up...

To set up a static route:

Click the Add button.
Type a route name for this static route in the Route Name field under the table.
(This is for identification purposes only.)
Select Private if you want to limit access to the LAN only.
Select Active to make this route effective.
Type the destination IP address of the final destination.
Type the IP subnet mask for this destination.
If this is for a single host, type 255.255.255.255.
Type the gateway IP address, which must be a router on the same segment.
Type a number between 2 and 15 as the Metric value.
This represents the number of other routers on your network. Usually, setting this to 2 or 3 works best, but if this is a direct connection, set it to 2.
Click Apply to enter the static route into the table.

Sorry to keep bumping this thread - but I have not been able to set this up. Does anyone have any pointers? I tried every combination of static route I could think of but no luck...

From memory, you'll need the ability to have two IPs on the WAN side of your router, the public passed-through WAN address, and an address on the same subnet as the LAN IP of the DrayTek. If you can't do that, you'll have difficulty getting it sorted with static routes.

Im trying to do the same thing but with an Asus rt-n56u router. No luck getting it to work.

I am not sure it is possible with the stock firmware. I got it working on my old WRT54GL running Tomato but had to add some special scripts (with help!). I don't think this sort of thing is possible without running Tomato or DD-WRT, which I might look at doing once I get 5 mins spare.

If your modem has a spare LAN port, you could try connecting it to the LAN side of your Netgear, and just set its IP to 192.168.1.254 so you can access it without needing to set 2 IPs on the Netgear's WAN interface. It should still route internet traffic to the WAN but will broadcast on the LAN to find the modem.

Nice idea Webwat - but I have the Draytek Vigor - it only has the one LAN port.

So you will just have to plug into the LAN whenever you need to configure the Draytec then.

Yep - or run DD-WRT firmware...I presume with that I can setup this sort of thing, like I was able to with Tomato? Just wondering if it is really worth all the hassle. The Draytek is pretty sweet - just sits there and works. Can always just cycle the power to reboot...
