Gentoo PPTP (VPN)

Jeg har en del tid bakset med en pptp forbindelse som skal laves fra en Linux Box (Gentoo 2.6.12) og til en server i verden.
Jeg skal herefter route al min forbindelse over denne, men når jeg kører en "pon" med debug aktiveret kan jeg se en række fejl, som jeg ik kan løse...

Se loggen:




$pon jaynet debug dump logfd 2 nodetach

Håber nogen kan finde en løsning...

Løsningen kan jeg ikke lige give, men du bør gøre det her for at troubleshoote:

Nogle routere kan ikke lide vpn. Så sæt en server op på lokalnetværk og prøv at forbinde til den. Eventuelt til localhost. Hvis den vil så er det sandsyneligvis routeren.
Det er et hyppigt problem for VPN både på linux og windows maskiner.

jamen det er ikke vpn serveren der fejler noget.
jeg sidder bag et NAT'et netværk, og andre pc'er (XP, Fedora, etc.) kan sagtens forbinde til den server...
