In order to prevent collateral damage to internal traffic, commit
c69c820025 introduced applying location
block on red0 as a sanity check.
On systems configured to use PPPoE, however, traffic appears on the ppp0
interface instead. This patch checks if a system is configured to use
this connection method, and applies the location filter to this
interface. red0 is used otherwise.
Fixes: #12519
