Quoting David W. Chapman Jr. (dchapman@houabg.com): > Does anyone know how to setup VPN or PPTP on freebsd?
I have a setup working with ppp over ssh. Scripts, netmap and ipfw info are available at http://www.ishiboo.com/~nirva/vpn/.
I had most of an OpenBSD<-->FreeBSD w/ OpenBSD IPSec patches VPN working, but the port of the patches seems to have broken something, and i can't get it all working.. KAME didnt support tunneling last I looked, maybe it does now... http://www.kame.net.
