The Zyxels are pretty good - isn't there a newer device in their portfolio that might suit? Netgear is also reasonable if you get the right model. I've heard some good comments about Billion but I've never used one myself. Also look at some of the more expensive routers that specialise in VoIP or security - just google for "Secure Router", "Security Router", etc. Many of them in fact have IPSEC built in, I got this:

The Actiontec C1000A has a transparent mode. It says it passes the
responsability of logging in to (in this case the linux machine) another
device. Could this be what I could do? If so can you direct me to
proceedures for this?

I have SSL VPN using a browser that works with this Actiontec C1000A.
Why is it that works and Openswan does not?

This device does not apear to have a phone jack to plug into the wall.
The two ports look like RJ45. How does this fit into my senario?
Thank you for all this help Alex,
