Network Address Translation
Network Address Translation (NAT) allows all PCs on your LAN to share a single public
Internet IP address. From the Internet, there is only a single device (the wireless VPN
firewall) and a single IP address. PCs on your LAN can use any private IP address range,
and these IP addresses are not visible from the Internet.
Note the following about NAT:
• The wireless VPN fire
wall uses NAT to select the correct PC (on your LAN) to receive any
incoming data.
• If you have on
ly a single public Internet IP address, you need to use NAT (the default
setting).
• If yo
ur ISP has provided you with multiple public IP addresses, you can use one address
as the primary shared address for Internet access by your PCs, and you can map
incoming traffic on the other public IP addresses to specific PCs on your LAN. This
one-to-one inbound mapping is configured using an inbound firewall rule.
Classical Routing
In classical routing mode, the wireless VPN firewall performs routing, but without NAT. To
gain Internet access, each PC on your LAN needs to have a valid static Internet IP address.
If your ISP has allocated a number of static IP addresses to you, and you have assigned one
of these addresses to each PC, you can choose classical routing. Or, you can use classical
routing for routing private IP addresses within a campus environment.
To view the status of the WAN ports, you can view the Router Status screen (see View the
System Status on page 300).
