We are using L2TP to connect our main location to a remote location. Our main location is the L2TP server.
A static route (IP>Routes) directs traffic destined for the remote network to the L2TP connection as gateway.
It appears that if the L2TP connection goes down, the route loses that gateway definition, even after the L2TP connection comes back up.
We are currently running 6.49.2, and the problem seems to have started sometime around the update to 6.48, possibly earlier.
