IPsec Verbindung jede volle Stunde ein Verbindungsabbruch

Hallo,

wir wollten unsere IPsec Tunnel nun von Watchguard auf Sophos umziehen. Es fiel bei manchen Verbindungen auf, das zu jeder vollen Stunde die Tunnel zu allen Remotedevices kurz weg sind (Egal ob das Remotedevice Juniper, Friztbox oder Lancom ist). Seltsamerweise ist im ipsec.log noch in den Logs der Remotedevices was zu sehen. Ich habe alles schon ausprobiert - Ohne Erfolg. Evtl. kennt ja jemdand das Problem und kann mir helfen.

Danke und Gruß

Joachim Müller

I'll guess that your policy uses an IPsec lifetime of 3600 seconds and that your setup or the other side doesn't have DPD enabled. It also could be a mismatch in lifetimes, so you should double-check your IPsec policy against theirs.
