4.5.19 Port Forwarding
Using the Port Forwarding page, you can provide local services (for example web hosting)
for people on the Internet, or play Internet games. When users send this type of request to
your network via the Internet, the router will forward those requests to the appropriate PC.
Port forwarding can be used with DHCP assigned addresses but remember that a DHCP
address is dynamic (not static). For example, if you were configuring a Netmeeting server,
you would want to assign this server a static IP address so that the IP address is not
reassigned. Also remember that if an Internet user is trying to access an Internet
application, they must use the WAN IP address. The port forwarding will translate the
WAN IP address into a LAN IP address.
To configure a service, game, or other application, select the WAN connection from the
Home screen, click Advanced, select Application, and select Port Forwarding. Next
select the IP of the computer hosting the service and add the corresponding firewall rule. If
you want to add a custom application, select the User category, click New and fill in the
Rule Name, Protocol and Port number for your application. . See Figure 4-33.
For example, if you want to host a Netmeeting session, from the Home screen, click
advanced select Application, select Port Forwarding. First select the IP address for your
Netmeeting server. Next select the Audio/Video category and add Netmeeting to the
applied rules box. To view the management rules, highlight Netmeeting and select view;
this will display the pre-configured protocols and ports that Netmeeting will use. Now
assuming that your WAN connection is correct, you can run Netmeeting from your server
and call users that are on the Internet. If they know your WAN IP address, users can now
call you. You should remember that Telkom ISP assigns a dynamic IP to your WAN port,
so your WAN IP is regularly changing. If you wish to have users outside the router (on the
internet) connect to a port that you have forwarded, they will have to know the current IP
address of the WAN port. A convenient way to overcome this is to make use of a Dynamic
DNS provider (see section on DDNS – 4.5.16).
