Chapter 17 Network Address Translation (NAT)

Selecting SUA means (latent) multiple WAN-to-LAN and WAN-to-DMZ address translation. That means that computers on your DMZ with public IP addresses will still have to undergo NAT mapping if you’re using SUA NAT mapping. If this is not your intention, then select Full Feature NAT and don’t configure NAT mapping rules to those computers with public IP addresses on the DMZ.
