Windows 2003 Routing Remote Access Question

I am trying to connect two networks by installing 2
network cards on windows 2003 server. The first network
connected to Watchguard firewall, and the second network
connected to Checkpoint firewall.

Everytime I connect to both LANs, the connection to
Watchguard terminated. If I unplug connection to
Checkpoint, the Watchguard connection come back online.
Because of this problem, I can only connect to one LAN.

I am trying to setup windows 2003 as network router
through routing and remote access, but I haven't been
successful so far. Anyone knows how to setup routing and
remote access for this kind of problem? or have any other
suggestion to connect this two LASNs?

Thanks for your help in advance.

This is probably caused by the default routes of the client machines. If
they are using firewalls to access the Internet, their default routes will
be set to point to the firewall. For this reason, no traffic will ever get
to the internal router.

A router between two subnets only works if the traffic actually gets to
the router. If there are no other routers, you simply make the router the
default gateway for each LAN. eg

192.168.1.x dg 192.168.1.1
|
192.168.1.1 dg blank
RRAS router
192.168.2.1 dg blank
|
192.168.2.x dg 192.168.2.1

If either subnet has a default gateway set to another router, you must
add extra routing to get the traffic to the internal router. eg

Internet
|
public IP
firewall
192.168.1.254
|
192.168.1.x dg 192.168.1.254
|
192.168.1.1
RRAS router
192.168.2.1
|
192.168.2.x dg 192.168.2.1

In this case, you would need extra routing to get traffic for
192.168.2.0 to the internal router. So you would need a route

192.168.2.0 255.255.255.0 192.168.1.1

You could add this route to every client in the 192.168.1.0 subnet. Or
you could just add it to the gateway router/firewall. The router would then
redirect the traffic to the internal router.

If both subnets use a firewall to the Internet, you would have to do
this at both firewalls, to get the local traffic to the internal router.
