Using the subnet on other interfaces breaks L2TP/IPSec
Open, NormalPublicBUG


Using a standard L2TP config from the wiki, if you have any IP on other interfaces in the subnet, the VPN will fail to route on new connections.

In my case, I had it on loopback for OSPF priority:

set interfaces loopback lo address

The /32 (which is what I meant to put), makes it work, but other subnet sizes don't

set interfaces loopback lo address
