3.7.5 Port Forwarding
When NAT mode is enabled as the WAN interface type (
), you can redirect a communication
request from one address and port number combination to another. Only the IP address on the WAN side is
open to the Internet. If a computer on the LAN is enabled to provide services for the Internet (for example,
work as an FTP server), port forwarding is required so that all access requests to the external server port from
the Internet are redirected to the server on the LAN.
To add a port forwarding rule, select the
Enable
check box and click on
ADD LIST
(Figure 37). Enter the
parameters per the field descriptions in Table 10.
