Is not a real Interface. A 'VPN' server, or client, goes over a physical, mostly WAN, interface.
If the 'main' physical WAN interface goes down, the underlying VPN also goes down.

combination of PPPOE
Nice example
Your pfSense WAN needs to be up, and ones it can talk to the other side, a modem probably, pfSense builds an PPPOE connection 'into' it.
One's that one is up and running, the VPN client now detects it has a WAN and gateway, and it can start to build into this tunneled PPPOE connection the a (tunneled) VPN connection.
Let's agree here : the KIS concept has been thrown overboard. Note says it's bad or so, just 'complicated'. And complicated things tend to be .....
When the WAN physically gets disconnects, everything comes crashes down ..., and has to be rebuild into the right order.
All this has nothing to do with "pfSense" or even the 4200 (powerful enough).
