Need Assistance - T1 Point to Point

[pchan]

I have two 1720 routers with a T1 in between location 'A' and 'B'. Also have a DSL connection at location 'A' which we get the internet. The problem is that any workstations in location 'A' or 'B' cannot get to any outside external address. Both routers can ping external addresses but not the workstations. The workstations do have the gateway set for these routers.

Thanks in advance for any assistance.

Here is the config for location 'A'.

I think you are missing a NAT stament or two if you are going from Private to Public ip's

dconstatino: it doesn't appear as though the internet is connected to that router so therefore the NAT would be on another router.

pchan: what addresses are your clients on?

I assume your DSL is connected to FE0 on Router A, correct? What is it connnected to? Is it a cable/dsl router? What is the IP on it? Your default route points to .1.254 so make sure the IP on the next hop is .1.254
What ip are the computers using for the gateway?

If the DSL is connected on FE0, where is the router connected to the LAN? The DSL router must be seperate.

 

[Degg]

It sounds like he has a cable/dsl router/switch connected to FE0, and the Lan is connected to the dsl router/switch as well. If this is the case, the gateway for computers on RouterA should be 192.68.1.254.

Also, I noticed you have RIP running, but have both Serial interfaces set to passive. This does no good, as neither router will pass RIP updates out it serial interface. You dont really need RIP anyways in my opinion.
