Strange VPN problem.
I have 2 tunnels between 2 ASL 5 boxes (tunnel A and tunnel B for 2 different subnets).
Everything works perfectly and the VPN is alive.
From time to time (+ - 36 hours) one of the tunnels is "trapped"
And it is always happens in tunnel B and never in tunnel A.
In order to fix that I have to restart the B tunnel from the web interface in both firewalls.
• Both tunnel use the same key and and IPSEC protocol.
• The lifetime is the same on both ASL boxes.
• One of the firewalls is behind NAT
Any solution?
