5-1. Advanced - Single Port Forwarding
Note: In the picture above, you will see an example of some port forwarding rules.
The Router can be configured as a virtual server on behalf of local services behind the LAN port. The given remote
requests will be re-directed to the local servers via the virtual server. This section deals with the single port
forwarding mainly. The Single Port Forwarding allows you to set up kinds of public services such as web servers, ftp,
e-mail and other specialized Internet applications on your network.
External Port : This is the external (WAN) port number for server or Internet application, for
example, port 21 for ftp service.
Internal Port : This is the port number of LAN computer set by the Router. The Internet traffic from
the external port will forward to the internal port. For example：you can set the
internal port NO.66 to act as the external port NO.21 for ftp service.
IP Address : Enter the IP address of the PC where you want to set the applications.
Protocol : Select the protocol (TCP/UDP/Both) for the application.
Note: If you do not know which protocol („Type‟) you need to select for your virtual server rule, select „Both‟.
This option will pass both TCP and UDP traffic through to the configured IP address.
