I don't known what is server, my suggestion is win2000/win2003 vpn server, i have only account. On openBSD firewall i also have vpn account using poptopd. Pftop show me that i use port 1723 tcp and 1723 udp. I thing that NAT is problem because VPN server try to connect to my ext_ip, where i block all in.That's my first filter rule.I have try and synproxy out packet to port 1723 without success.
any suggestions? Best regards T.Ganev ===== http://wwwkeys.pgp.net:11371/pks/lookup?op=index&search=0x300D6655&fingerprint=on Key fingerprint= 2499 DE87 82ED 23A8 FD20 3078 04FE 610E 300D 6655 __________________________________ Do you Yahoo!? Check out the new Yahoo! Front Page. www.yahoo.com
