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.

As mentioned above, Port Redirection can redirect incoming TCP/UDP or other traffic on
particular ports to the specific private IP address/port of host in the LAN. However, other IP
protocols, for example Protocols 50 (ESP) and 51 (AH), do not travel on a fixed port. Vigor
router provides a facility DMZ Host that maps ALL unsolicited data on any protocol to a
