Figure 26b: Advanced Features
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 XC-DPG Twin WAN
Router needs 2 addresses, 1 for the LAN port, and 1 for the WAN port.)
•
Generally, NAT is disabled only when you wish to use the XC-DPG Twin
WAN Router as a Static Router.
