NAT Configuration

NAT Routing
NAT (Network Address Translation) is the technology which allows one (1) WAN (Internet) IP address to be used by many LAN users.

If you disable NAT, Internet access is only possible if all PCs are configured with valid Internet IP addresses. (The Twin WAN Gateway needs 2 addresses: 1 for the LAN port and 1 for the WAN port.)
NAT is disabled only when you wish to use the Twin WAN Gateway as a Static Router.
