Setting up VPN with TomatoVPN?

Hey guys, looking for some help in setting up a VPN on my WRT54G running Tomato VPN.

I've found lots of guides on Google but none really target TomatoVPN - there are guides on OpenVPN, and guides about DDWRT, but I can't seem to figure out how everything goes together. I also want to try and do this right the first time since it's a big hassle testing VPN as I have to physically be on another network to see if it's working or not.

Can anyone guide me through the process? Thanks!

Bump! Anyone?
