FreeBSD VPN HOWTO
Anton R. Ivanov: ai1-u at sigsegv.cx
This document tries to cover as much of the currently available FreeBSD VPN functionality paying attrention to some of the most common problems and caveats. It does not try to cover all of them and it does not try to be a "cookbook". If you want to cut and paste without understanding what are you doing you are in the wrong place. You should use a suitable commercial solution instead. One of these ( 1, 2, 3) will do nicely.
