Re: VPN Client (PPtP) behind OpenBSD 3.0 doing NAT..

[Gary S MacKay <gary@edisoninfo.com>]

         I fought this for a few days too. I finally went back to OpenBSD 
2.9 which worked just fine. Maybe a future 3.x version will work, don't 
know. I think it is a problem with the pf program which just hasn't matured 
enough yet. I do know that I liked the 3.0 version alot better and swear it 
was faster. Unforturnately, I have to have the vpn working for my clients.

If you get 3.0 working, please let me know how.
