Multiple home routers and Subnet help 2

July 1, 2010 at 22:13:58
Specs: Windows XP

Hello. I am trying to do exactly what the original poster in this thread (http://bit.ly/9ZoKk5) was asking about. I followed Curt R.'s howto here (http://bit.ly/allHzQ), but it's not working. Router 2 is a WRT54G. Router 1 is a M0n0wall.

Everything is set as per Curt's instructions, but I can't get router 2 clients to see the internet. If I change the "operating mode" in "advanced routing" from "router" to "gateway", the router 2 clients are able to see outside - but then they also are able to see the clients on router 1 (despite the different 192.168.0/1.x client IP addresses).

Any thoughts on how to get it working? Thank you very much!

I suspect you've created a static route between subnets on router 2 (downstream). If you did, and you remove the route then the clients won't be able to communicate with each other.

I am the captain of my soul.

Lets start with posting a ipconfig /all from a pc off router2 when router2 is set as router and when set as gateway.

Under each router config do a tracert to the wan ip of router1 and post those also for review.

If I did it wasn't intentional! Maybe the router did it on it's own? Anyway, under "advanced routing/routing table" it shows this.

Since I didn't manually add anything, I don't see how I could delete any routes.

Thanks.

Also please note that I reversed router 1 and 2 subnets from Curt's tutorial because router 1 (and existing network) was already set up as 192.168.1.1.

Thanks.

tracert as gateway:
Tracing route to cpe-xx-xx-xxx-104.kc.res.rr.com [xx.xx.xxx.104]

over a maximum of 30 hops:

1 <1 ms <1 ms <1 ms 192.168.0.1

2 1 ms 1 ms 1 ms cpe-xx-xx-xxx-104.kc.res.rr.com [xx.xx.xxx.104]

Trace complete.

Are you able to ping the DNS server...

Ping 192.168.1.1

I am guessing not because it is on a different subnet unless you setup the router to route between the two networks.

tracert as router?

I would not list x.x.1.x as dns. It should be x.x.0.1
