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:
version 12.2
no service pad
service timestamps debug datetime msec
service timestamps log datetime msec
service password-encryption
!
hostname 2600router
!
!
ip subnet-zero
no ip source-route
ip cef
!
!
no ip domain-lookup
ip name-server 1.2.3.67
ip name-server 1.2.3.68
ip name-server 12.1.2.130
ip name-server 12.1.2.131
!
!
!
!
interface Multilink1
ip address 2.3.4.78 255.255.255.252
no keepalive
no cdp enable
ppp multilink
no ppp multilink fragmentation
multilink-group 1
!
interface Ethernet0/0
description connection to customer LAN
ip address 1.2.3.129 255.255.255.128
no ip redirects
no ip unreachables
no ip proxy-arp
no ip mroute-cache
full-duplex
no cdp enable
!
interface Serial0/0
no ip address
encapsulation ppp
no cdp enable
ppp multilink
multilink-group 1
!
interface Serial0/1
no ip address
encapsulation ppp
no cdp enable
ppp multilink
multilink-group 1
!
ip classless
ip route 0.0.0.0 0.0.0.0 Multilink1
ip http server
ip pim bidir-enable
!
!
no cdp run
!
line con 0
line aux 0
!
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.
