Network Address Translation (NAT)

6.1 Virtual Servers

Click Advanced Setup > NAT > Virtual Servers to open the screen where you manage the list of
virtual server rules.
A virtual server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that
you can make visible to the outside world even though NAT makes your whole inside network
appear as a single computer to the outside world.
Note: Many residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may
periodically check for servers and may suspend your account if it discovers any
active services at your location. If you are unsure, refer to your ISP.
