Forwarding
Port forwarding can be used to set up public services on your network. When users from the Internet make certain requests on your network, the Router can forward those requests to computers equipped to handle the requests. If, for example, you set the port number 80 (HTTP) to be forwarded to IP Address 192.168.1.2, then all HTTP requests from outside users will be forwarded to 192.168.1.2. You must disable the Router's DHCP function to utilize port forwarding.
You may use this function to establish a Web server or FTP server via an IP Gateway. Be sure that you enter a valid IP Address. (You may need to establish a static IP address with your ISP in order to properly run an Internet server.) For added security, Internet users will be able to communicate with the server, but they will not actually be connected. The packets will simply be forwarded through the Router.
To add a server using forwarding:
To delete a server entry:
UPnP Forwarding
UPnP forwarding can be used to set up public services on your network. Windows XP can modify those entries via UPnP when UPnP function and UPnP control under Password Tab are all enabled. Add and Delete UPnP Forwarding entry is same to Port Range Forwarding, but user can have different port number for external and internal.
Port Triggering
Some Internet applications or games use alternate ports to communicate between server and LAN host. When you want to use those applications, enter the triggering(outgoing) port and alternate incoming port in this table. The Router will forward the incoming packets to the LAN host.
