OpenVPN läuft... oder auch nicht

[sYchZ]

Hallo zusammen,

habe leider einige Probleme mit dem OpenVPN. Würde gerne meinen kompletten Dreambox Traffic über einen VPN laufen lassen. Habe alles entsprechend angelegt keys, cert, conf, etc. und läuft auch... jedoch nur fast.
Leider kommt es in unregelmäßigen Abständen zum Abbruch der VPN Verbindung und ab dann läuft der Traffic wieder normal, aber nicht mehr über den VPN. Vielleicht könnt ihr mir weiterhelfen?
