I'm looking for an inexpensive VPN appliance that supports PPTP. I've found a few that do IPSec, but I want to be able to use the built-in PPTP client in Windows. I know I can use Windows Server or Linux for this, but I don't want to use a full blown PC or server for this.
What products are out there that fit into a shoestring budget?
We use pfSense and m0nowall for this - simple to use web-based admin. You can use an old PC with a Disk on Module in the IDE connector or a single-board-computer like ALIX from pcengines. Found this solution to be cheap and reliable.
