Port Forwarding allows the option to run a publicly accessible server on the LAN by specifying the mapping of TCP / UDP ports to a local device. This enables incoming requests on specific port numbers to reach devices such as Web Servers, Mail Servers, and Digital Video Recorders (DVR).  Some services are predefined under the Commonly Forwarded Ports or be manually configured through the entry.  This document contains the following sections:
NOTE 1: It is recommended to manually configure the TCP / IP settings on the server that will be remotely accessible. If this is done, then it is mandatory to configure the following settings:
- IP address
- Subnet mask
- Default gateway
- At least one DNS address
If the following settings are configured without the default gateway, remote access to the server will not be available, as it will only be accessible from the local network.
NOTE 2: When manually configuring the TCP / IP settings on a device, make sure that the DHCP pool in the SBG6580 doesn't include the IP address of the server.Â
NOTE 3: If the firewall is set to High or Medium, port forwarding feature will be inoperable. Â The firewall needs to be set to Low to function.

- On the Advanced - Port Forwarding page:
a.  External IP Address & Start/End Port - Leave at 0.0.0.0. This will allow incoming traffic on the specified ports from any remote IP address. This is sufficient for most setups. Then enter the desired port number and re-enter the desired port number.
     NOTE 1: If it is desired to allow incoming traffic on the specified ports from only one remote IP address, enter that IP address for the External IP.
      Â
     NOTE 2: If it is desired to forward a range of ports, enter the first number of the range for Start Port, and the last number of the range for End Port.Â
Â
b.   Local IP Address & Start/End Port - Enter the IP address of the device. Then enter the desired port number and  re-enter the desired port number.
      NOTE: If it is desired to forward a range of ports, enter the first number of the range for Local Start Port, and the last number of the range for Local End Port.
c.  Description -  Enter a desired name.
