Problem pinging

[rlgaooa]

I am having a problem pinging through a router configuration I just built. Within the Cisco console I can ping from fastethernet interface to interface. From a machine in the same subnet as the router I can ping the fastethernet interface but can go no further. I have enclosed my routing configuration in case you can spot something I have missed.

Not sure what your layout/design is here? You don't supply a lot of information in your description of the problem. You are trying to ping machines behind fastether 0/0 or what other interface?
What is this in there for; ip route 172.18.1.0 255.255.255.0 172.20.2.24 , is 172.20.2.24 the next hop? If so is it pointing back to 172.18.1.0? Because if it isn't then your packets coming from 172.20.2.24 don't know where to go and you need to add a route on that machine as well. A simpler notion would be to add 172.18.1.0 to the RIP2 protocol you have running (that is if rip is running on all of your machines). These are just some guesses as I don't have a full understanding of your question.

Thank you for responding so quickly, I am attempting to connect three remote sites to one main site. I have placed one router (2650branch) at a remote site. It's internal network segment is 172.20.1.0. I need to pass all non 172.20.1.0 traffic to the main office. It's network segment is 172.18.1.0. I am using point to point T1 lines. Main Network 172.18.1.0 --- Router 172.20.2.24---T1---172.20.2.20 Router--- 172.20.1.0 Branch Network. I am trying to ping from 172.18.1.0 to 172.20.1.0. I'm not sure I need to have a static route or that if I do I have it configured correctly.

Configure rip version 2 and no auto-summary on 2650main and remove the static routes from both router if possible.Since you are running rip static routes not required

Are you able to ping the serial and Ethernet IP's of 2650branch from the 2650main and vice versa ?If this works then check the defaultgateway of the Machines from which you are pinging.Should be routers eth IP.
