I configured a VPN using Ubuntu 19.10 and network-manager-l2tp 1.2.10. After struggling with enabling the correct phase1 and phase2 settings I now get a connection. That connection gets torn down after less than a minute.
Looking at the routing table I see that something adds a ppp0 route to the IP of the gateway I am connecting to. That breaks the communication to the gateway as that route is above the one that uses the correct wireless interface to make it continue to work. Any ideas of what could be happening?
