Every type (server or client) of connection has name l2tpX
on the same digital index, the connection name may coincide, which will lead to the inoperability of this connection

Subject changed from overlay of names of network connections to L2TP Server and Client both use "l2tpX" for interface names
Category set to L2TP
Priority changed from Normal to Very Low
Affected Version set to All

I see what you mean and have adjusted the subject to match. Both the L2TP Server and L2TP interfaces use "l2tpX" for the interface names.

PPPoE avoids this by using "poesX" for the server interface names and "pppoeX" for clients.

Given the rarity of both the L2TP server and client being in use on the same firewall, this doesn't seem like it would affect many people. L2TP client use is already rare, and few people use the L2TP server as well.

PPPoE server uses "ngX" for interface names, another issue

Fix:
https://gitlab.netgate.com/pfSense/pfSense/-/merge_requests/37
it also hides l2tp server interfaces from interface list
