Enable

Check this box to enable such port redirection setting.

Mode

Two options (Single and Range) are provided here for you to

choose. To set a range for the specific service, select Range. In

Range mode, if the public port (start port and end port) and the

starting IP of private IP had been entered, the system will

calculate and display the ending IP of private IP automatically.

Service Name

Enter the description of the specific network service.

Protocol

Select the transport layer protocol (TCP or UDP).

WAN IP

Select the WAN IP used for port redirection. There are eight

WAN IP alias that can be selected and used for port redirection.

The default setting is All which means all the incoming data

from any port will be redirected to specified range of IP address

and port.

Public Port

Specify which port can be redirected to the specified Private IP

and Port of the internal host. If you choose Range as the port

redirection mode, you will see two boxes on this field. Simply

type the required number on the first box. The second one will

be assigned automatically later.

Private IP

Specify the private IP address of the internal host providing the

service. If you choose Range as the port redirection mode, you

will see two boxes on this field. Type a complete IP address in

the first box (as the starting point) and the fourth digits in the

second box (as the end point).

Private Port

Specify the private port number of the service offered by the

internal host

Note that the router has its own built-in services (servers) such as Telnet, HTTP and FTP etc.

Since the common port numbers of these services (servers) are all the same, you may need to

reset the router in order to avoid confliction.
