Hello folks, first time poster here. I am trying to get a solution to a problem - I hope someone out there can help.

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

ip http server
ip pim bidir-enable

no cdp run

line aux 0

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

I have not changed my DNS IPs with my registrar as of yet. I do have a LAN connected DNS machine that is changed to the new IP scheme.

Thank you. I can provide any more needed info.

what device is performing NAT??

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

I don't have NAT setup on this router. I am using a Mikrotik box for that (it is not changed over yet). The machine that I am trying to get a connection on first has a static IP on it.
