Thanks for the reply.
The bridging option slipped my mind because the current interface to
the IPCOP distro doesn't allow it from the config webpage... no big
deal... i can edit the configs myself, so i may end up using this
If I keep the routed option and ant to set up my static routes....
setting up the routes on those two routers is exactly what I thought.
Unfortunately it doesn't work, and I think it's because my ISP is using
private IPs for their equipment management. Even though I have real
public IPs, if I do a traceroute from my gateway to say yahoo.com, I
get their private management addresses and I think the routers are
getting confused somehow. The first is my gateway, and the next three
belong to my ISP.

This should be solvable too...I'll keep at it. I've used other VPN
equipment and the most conceptually simple way I've seen things is that
the VPN device has an external IP and a real internal IP. When clients
join, the interface that handles the real internal IP is aliased to
also take on the IP of the client that is connected; ten clients = a
physical nic with ten aliases. I guess this really would be a question
for the openvpn guys, but it seems it would be a lot slicker way to do
