routing question on cisco 1800 static ip port

[randy kruen]

Hi Everyone. First of all, I am not a cisco expert, and I appreciate your time here.

I am running a cisco 1841, with a wic1dsu-t1, and a hwic 4 esw card.

I am remote, and have a setup where my ethernet comes in from about 30 kilometers away on a T1 to a my T1 card port serial0/0/0.

I have a 4 port ethernet card configured to give dhcp ip addresses to serve my devices. All works good.

I would like to configure the 2 built in ports fastethernet0/0 & 1 to static ip addresses and seem to be missing something in the routing.

The near side of my serial (T1) connection is ip 192.168.2.1. The far end of the serial connection is ip 192.168.2.2.

From any of the 4 ports on the ethernet card, I am able to ping through to the far end no problem.

From either of the built in ports 0/0 or 0/1, I can only ping to the near side of the serial connection, 2.1. I cannot ping to the far side of the serial connection, 2.2. What am I missing?

Thanks very much for you time in assisting me with this!

Randy

Hello,

Do you have return routes toward 192.168.4.0 and  192.168.3.0 on the other router?

Please share the configuration of the other side.

IP route 192.168.3.0 255.255.255.0 192.168.2.1

IP route 192.168.4.0 255.255.255.0 192.168.2.1

I do not! I can add these in if that is my issue. Far end config is as follows:

Cisco 1700 series, ethernet side faces outside world, serial side faces me.
