IPsec tunnel going down at specific times

[seanbakers]

Hi

i have a Ipsec tunnel between a ASA 5510 (Uk) & a router (France) that seems to be going down a specific times during the day. I have attached the sys log as well.

I cannot seem to copy & paste the config onto here for some reason so i have attched the configs, Ipsec details & syslog details from the asa.

Hi,

From my experience, if you're connecting ASA with router, is't very important to have all settings configured same.

At first look, on UK side is PFS used, and on FR side I can't see it configured.

Also check defalut settings for lifetimes of IPSec on both sides (IKE seems to be ok, if tunnel goes up...).
