Hi, I am having some problems getting Terminal Service and FTP traffic to work over an ISDN link. I am using Dailer Watch to back up a T1 lease line. When I drop the T1 and ISDN dials up and routes are learn via OSPF. ICMP seem to work fine so does traffic from a non natted subnet on the remote side (R2 and R4). I think it is a natting issues but the natting config is the same as the one on the T1 router. Everything works fine over the T1.
R3 and R4 are running IOS 12.2(6f)
R1 and R2 are running IOS 12.2(1)
Here are snap shots of the four routers. SPID and Telephone are remove for security. R1 and R2 are connected via T1 circuit and R3 and R4 are connected via the ISDN. R3 and R1 are connected via ethernet and R2 and R4 are connected via ethernet.
Jeffrey, thanks for the response. The 10.100.131.234 is not the the problem here is work fine on the lease line.
The configuration is working now as I would like it to. Not sure but still reseaching. Prior to posting this, on the router receiving the call I had the "default-information originate always" that has been removed.
