I have an FVS328 in our main office which I have just configured for Internet access and VPN links to FVS318s at our remote offices. The VPNs are working except that after a few hours they will stop passing data. Attempting to ping across the VPN will not bring them back up. I go into the VPN status on the FVS328 it says; Phase 1:M-ESTABLISHED/Phase 2:IDLE.
It seems that because phase 1 is established it considers the vpn as connected. If I click on the drop button then the line will reconnect as soon as it detects any data needed to pass over the vpn.
Any help welcome.
