routing two lans

Hi everybody.

I have got some problems about routing with W2000 Servers.

The scenario is this:

** LAN1: 192.168.1.0
- PC1, IP 192.168.1.2
- W2000 Server called Server1 with 2 network cards, so it has two ips:
192.168.1.1 and 192.16.10.161

** LAN2: 192.168.20.0
-PC2, IP 192.168.20.162
- W2000 Server called Server2 with 2 network cards, so it has these ips:
192.168.20.159 and 192.16.10.159

** LAN3: 192.16.10.0
This is the main lan of the office. Here there is an ADSL router with ip
192.16.10.11.

Both w2000 servers have RRAS enabled, with NAT.
Here there are the routing tables for these servers:

192.168.20.159 1
Default Gateway: 192.16.10.11


********* PROBLEM:

So, I can ping 192.16.10.11 from any computer. I can ping 192.16.10.159 from
PC1 and Server1. I can ping 192.16.10.161 from PC2, but...

I can't ping 192.168.20.162 from PC1 and Server1, even I can't ping
192.168.20.159 from PC1 and Server1. So both LAN1 isn't reachable from LAN2
and LAN2 isn't reachable from LAN1 although I can ping 192.16.10.x address
from both LANs

NAT is set up on both servers (in fact, If I didn't set up then any PC can't
ping any computer working outside their lans).

Can anyone help me?

Thanks in advance, regards


B.T.

You have a good route on each server to the opposite LAN . So providing
that the clients have the correct default gateway and masks to troubleshoot
this it's probably good to remove NAT and just setup a plain router on each
of the servers.

1. Turn off NAT.
2. Configure a "plain" router.
3. Verify the correct routes on the server, and the correct default gateway
on the clients.
