Input validation prevents 1:1 NAT rules on IPSec
Additional input validation in the GUI in 21.02/2.5 prevents creating a 1:1 NAT rule on the IPSec interface because it expects an IP family and enc doesnot have one:
The following input errors were detected: The interface do not have address from the specified address family.
Should also read "interface does not have address".
This is an edge case because NAT is not expected to work on IPSec. However there are situation where us can work and did in pfSense < 2.5.
Specifically if the P2 in use carries 0.0.0.0/0 it will carry the NAT'd traffic still.
This only applies to 1:1 NAT
