Hey,
i have a problem with routes. VPN works everytime some days long well, but after (lets say 3-7 days) i have usually a routing problem. If that problem occures, the clients cant ping to the server. I have attached a two pictures so you can see the routes if everything is okay und the routes by failure.
The problem is, after that days the secound route from above changes from:
10.10.100.0 255.255.255.0 10.10.100.2
10.10.100.1
to:
10.10.100.0 255.255.255.0 10.10.100.2
192.168.178.49
192.168.178.49 is the real network interface ip. 10.10.100.0 is the virtual interface of my vpn.
After restarting the server service, everything works fine. Some idea why that routes is changing after some days?
Here the working routes:

Here the routes by failure:
