2610 and multilink problems

jakkwb

Hello folks, first time poster here. I am trying to get a solution to a problem - if this is not the right place, please forgive.

I am moving from a single T1 to 2 T1s with the same provider. I am having to change my entire IP scheme. I have a Cisco 2610, software 12.2.

My provider is using multilink for the T1s. MY router has 2 wic cards in it. I have had it configured several times now. The interfaces both come up with no indicated problems.

I can ping any IP from the router. However, I cannot ping or traceroute from a LAN connected PC to anything past the next hop from me (the providers router).

Here is my router config. The IP numbers have been changed:

Does anyone see anything wrong with my config that would cause this problem?

Thank you. I can provide any more needed info.

Can you ping the providers next hop from the LAN? If you can it sounds like they don't have your route built except on the edge router.

Yes, I can ping the IP of the router on the other end of the circuit from a LAN connected PC.

That is exactly what I have been thinking. Provider has not seen it this way as of yet.

Thanks for your help.
