Ok here is some more infromation about my routers!

[Guest_imported]

I have a point-to-point connection established and working great. I have a Cisco router on each end. Everyone at the remote location can login to the network(Windows NT) but they can't get internet. My internet is T1 access behind a SonicWall Pro firewall at address 172.20.1.205. I setup routes: 0.0.0.0 0.0.0.0 172.20.1.205 but it still doesn't work. If anyone has suggestions I would greatly appriciate it. Here are my router configs:

Main Location:

memory-size iomem 25
ip subnet-zero
no ip domain-lookup
!

interface Serial0
description Point-Point
bandwidth 768
ip address 192.168.2.1 255.255.255.0

end

Remote Location:

no ip directed-broadcast
no cdp enable

interface Serial0

no logging buffered
no cdp run
!
line con 0
line vty 0 4
password $simba
login
!
end

My firewall has 1 route: 172.20.2.0 255.255.255.0 172.20.1.200

What should my gateway be for the remote locations workstations? Now I have 172.20.1.200!

First, think of your gateway address as an exit point from one subnet to another. So, the gateway address will need to be in the same subnet as the host.

I tried drawing out your config, so I'm thinking you're set up like this:

172.20.2.0 /24 = Remote users
192.168.1.0 /24 = P2P link between routers (I'm assuming the 192.168.2.1 is a typo.)
172.20.1.0 /24 = Local users
172.20.1.205 = firewall address

If my understanding is correct, then I'd try this.

Remote users' gateway = 172.20.2.30
Remote router gateway = 192.168.1.2
From that point on, the local router's gateway will take over.

Each subnet has a gateway to the next subnet.
