We have a vehicle which connects to our internal wireless network whilst on any of our sites. The minute the vehicle leaves our sites and the wireless drops, it then connects via LTE (ipsec vpn initiated) to our main firewall (SG330 Cluster). The vehicle uses a draytek 2960 ln (multi wan with built in LTE)
The UTM is setup for respond only as the vehicles ip is dhcp via LTE. The setup looks fine and vpn etc is established on demand.
However, what we find is that sometimes the vpn connects and will not pass traffic. Turning the draytek off and on results in the same ie tunnel established but no traffic.
If we do the same at the UTM end ie turn the connection off and on, everything then works which leads me to believe that the issue and solution is at the UTM side of things.
Any ideas?
