Routing Mode
Routing between the LAN and WAN will impact the way this router handles traffic that is received on any of
its physical interfaces. The routing mode of the gateway is core to the behavior of the traffic flow between the
secure LAN and the Internet.

With classical routing, devices on the LAN can be directly accessed from the Internet with their public IP addresses
(assuming appropriate firewall settings are configured). If your ISP has assigned an IP address for each of the
computers/devices that you use, select
Classical
.
NAT is a technique which allows several computers and devices on your local network to share an Internet
connection. The computers on the LAN use a “private” IP address range while the WAN port on the router is
configured with a single “public” IP address. Along with connection sharing, NAT also hides internal IP addresses
from the computers on the Internet. NAT is required if your ISP has assigned only one IP address to you. The
computers/devices that connect through the router will need to be assigned IP addresses from a private subnet.
