VPN verbinding verbreekt (geen ICS, nl. SP2)

[Verwijderd]

Ook bij mij net als bij velen een VPN verbinding die na korte tijd verbroken wordt. Ik heb een Windows XP Pro SP2 machine achter een Medion draadloze router zitten die op zijn beurt het Speedtouch 510 modem gebruikt. De VPN verbinding komt prima tot stand, maar wordt na een paar minuten verbroken. Ik heb geprobeerd de machine met ping -t te pingen; de disconnect wordt hiermee uitgesteld maar niet vermeden, uiteindelijk wordt de PPP verbinding verbroken. Ik heb ook de PPP tracing even aangezet en (een gedeelte van) de log toegevoegd.

Iemand?

Ik heb het nooit zo op een 510 als het om PPTP vpns gaat eerlijk gezegd..
Volgens mij droppen die GRE te snel.

Je zou ook in windows kunnen kijken naar de MTU waarde. Ik werk ook met vpns en een 510 en dit heeft de problemen erg verminderd...
