Description

How to recreate:
Create L2TP VPN
Create a default gw to the VPN subnet
Create the static route
  • route is added to diagnostics -> routes
    Disconnect from VPN
  • route is deleted from diagnostics -> routes
    Reconnect to VPN
  • route is not re-added
    Disable the static route
    Enable the static route
  • route is added to diagnostics -> routes

The static route should be automatically re-added when the L2TP interface is up.
I'm not sure if this is an intended behaviour, I googled it, and I didn't found anything related to this - so I assume that this is a bug.

The L2TP WAN-type interface design is not designed to be used with VPNs. It may work, but not intentionally. It is designed to be used for ISPs which require it for WAN connectivity.

Though the routing behavior as stated is undesirable, I don't see us putting internal resources toward supporting this use case.

If someone wants to submit a PR to correct the behavior, we can certainly consider it.

route is not deleted if reconnecting.

Static route will be deleted if L2TP interface is down.

Static route will be added if L2TP interface is up/reconnected.
