want to make them publicly accessible. With NAT applied, the internal IP
addresses of these servers will be translated to a single IP address that is
unique on the Internet. The NAT function not only eliminates the need for
multiple public IP addresses, but also provides a measure of security for
your LAN/WLAN.

When the HN294d receives an incoming IP packet requesting access to
your local server, the router will recognize the service type according to the
port number in this packet (e.g. port 80 indicates HTTP service and port 21
indicates FTP service). By specifying the port number, you tell the router
which services should be forwarded to which local IP addresses you
specify.

NOTE! After you have set up a virtual server you should modify the
filter rules for those ports and services you set up on the virtual
server. This is because the firewall uses these filter rules to protect
the route.

In the virtual server list table, you may modify or delete an entry by simply
clicking the Modify or Delete link for that entry.
