If you want an inexpensive firewall/VPN type router, I would recommend the Webram[p 700s that was all over the Hot deals forum months back.
Flash it to the sonicwall firmware 5.1.7 and u have an Orginal SOnicwall soho that wil not only allow you to set up endpoint VPNS with other Sonicwalls, but allow you access VIA software client for VPN as well. That and u get a nice firewall which wil allow ACL's both in and out, content filtering by keyword, time of day, One-to0-One NAT if needed, etc.
Have seen them on Ebay for $75 or so with unlimited user/VPN features enabled.
I really like mine!
