IP Sec Meldung

[superwinni2]

Hallo zusammen


ich bekomme im 10 Sekunden Takt immer folgende Meldungen in die IPSec Log.
Kann mir jemand sagen warum?

Die Verbindung funktioniert meines Wissens nach durchgehend stabil.
Es beklagt sich zumindest niemand über Verbindungsabbrüche... 


Leider habe ich keine Ahnung was auf der gegenüberliegenden Seite für eine FW im Einsatz ist. Ebensowenig weiß die Person auf der anderen Seite was genau sie macht. Ich möchte gerne ausschließen, dass ich der schuldige bin.


Damit man nicht so viel scrollen muss habe ich vorne Datum, Uhrzeit hostname und prozess sowie ProzessID entfernt.
Dafür schreibe ich es einfach mal hier hinein:
