Dear all
We are trying since days to establish a VPN connection between Fortigate 80C and FritzBox.
Fritzbox uses IpSec and has poor possibilites to monitor the connection.
We talked to both manufaturers. Both say that the configruation ist ok.
But the connections always is blocked and can not be reestablished after 3600 seconds, which is the given intervall to renegotiate the key.
Only if the session on Fortigate is killed and restablished the VPN connections works again.
Where is the error? Anybody an idea?

What amount of time do you have established for the clients to renew their IP address (lease) in your router? Looks a possible 1 hour lease limit (3600 seconds) could be causing this to happen. Change to a higher time and see it that helps.

Good luck!
