Hello All,

I have a conflict. I have come across this problem twice in the last couple months and am hoping somebody might be able to shed some light.

I have a client using a WatchGuard Edge FireBox 700. I have a few site to site VPN tunnels set up. For some reason every 10 or so hours the VPN link goes down. I have spent hours playing with Keep Alive Values and it has not improved. It almost appears that after a certain amount of inactivity or a network hicup the VPN tunnel breaks. I am very aware that IPSEC tunnels are very sensitive (UDP) but this firewall does not seem to initiate an IKE handshake automatically to rebuild the tunnel.. so I am forced to manually reboot it to force a rebuild.

any help or insight would be appreciated.
