Consider a scenario where WAN1 is used for internet connectivity. NAT must be enabled
at WAN1 to enable LAN systems to access the internet. The company’s servers
(Web/FTP Server) may be installed at the DMZ interface using public IP Address for
direct access from the internet. NAT should not affect the traffic between DMZ and
WAN1, because DMZ systems are already using public/global IP Addresses. In this case,
NAT can be disabled between DMZ and WAN1.
Say WAN2 Port is used to connect some PCs or IP Phones with global IP Addresses. In
this case, NAT is required only for traffic between LAN and WAN1. NAT can be
disabled between WAN2 and WAN1 since WAN2 systems already use global IP
Addresses.
