NAT loopback Configuration
In order to run the NAT loopback on ZyWALL USG, please add these rules after you
finish the 1-1 NAT mapping.
Firstly, add one Virtual Server rule for LAN usage. All the parameters are the same as
those set on 1-1 NAT mapping, except the Interface item.
In total there are two Virtual Server rules in this case.
If you put the Web Server on DMZ and access from the LAN, this configuration will
do as you requested. However, if you put the Web Server on LAN and access from
the LAN, you need another Policy Route rule to realize it.
