Routing problem -- what am I doing wrong?

[chiacomo]

I have two location and three routers laid out in the following pattern:

HTI2 <-> HTI1 <-> Vo2 <-> (internet)

HTI1 and Vo2 are in the same location on the same subnet.

HTI2 and HTI1 are connected via T1 (Serial).

I cannot reach the internet from HTI2.

HTI1 LAN is 10.100.40.126 (Netmask is 255.255.255.128)
HTI1 Serial is 192.168.100.1

Vo2 LAN is 10.100.40.1 (Netmask is 255.255.255.128)

HTI2 LAN is 192.168.20.1/24
HTI2 Serial is 192.168.100.2

HTI1 Routing:
ip route 0.0.0.0 0.0.0.0 10.100.40.1
ip route 192.168.20.0 255.255.255.0 Serial0/0

Vo2 Routing:
ip route 192.168.20.0 255.255.255.0 10.100.40.126

HTI2 Routing:
ip route 0.0.0.0 0.0.0.0 10.100.40.1
ip route 10.100.40.0 255.255.255.128 Serial0/0

This is dumb but I've been trying several things -- I've changed the 0.0.0.0 routing HTI2 to point to Serial0/0 and 192.168.100.1 -- nothing changes. What am I missing? Oh -- and I've not got direct access to these routers; I'm trying to talk a "manager" through this on the telephone.

HTI2 route only needs to be:

ip route 0.0.0.0 0.0.0.0 192.168.100.1

HTI1 should have:

ip route 0.0.0.0 0.0.0.0 10.100.40.1
ip route 192.168.20.0 255.255.255.0 192.168.100.2


That's it. I assume though that you have NAT rules on your firewall/router (Vo2) - are you sure these allow 192.168.20.0/24 as well as 10.100.40.0/25?
