Description

When enabling and configuring the L2TP server, I noticed that it creates duplicate entries in outbound NAT for the remote address subnet.

Per this forum thread: https://forum.netgate.com/topic/150290/duplicate-outbound-nat-entries-when-creating-l2tp-server Jim Pingle suggested this might be unintended duplication:

Looks like there may be an unintended duplication there.

It gets added to $FilterIflist at https://github.com/pfsense/pfsense/blob/master/src/etc/inc/filter.inc#L1179

And then manually added to the NAT network list at https://github.com/pfsense/pfsense/blob/master/src/etc/inc/filter.inc#L1664

I've attached screenshots attached showing issue.

This occurs in 2.4.4-p3, 2.4.5-RC and 2.5.0
