Should I enable NAT loopback?

The main benefit of NAT loopback is that it allows one to treat the router’s WAN address as if it were in a LAN. This is beneficial if you have a hostname connected to the IP address of your WAN or just if you want to be able to access services via your WAN address instead of dealing with the internal LAN address.

What is masquerade for WAN?

For a WAN port, what masquerade does is allocate an unused port for the WAN public interface, change the source addr of the exiting packet to the WAN public addr, change the source port to the allocated port, and create an association between the allocated port and the original addr/port pair unless such an association …
