Easy Port Forwarding: Applying Pre-Defined Rules

WAN Connection: refers to the active Connection Profile.

LAN IP: refers to the local Router IP address; the NB5 Default IP is shown in this example.

New IP: If you wish to manually add a LAN client so that you can apply rules to it, click on the New IP Button and enter Host Name and IP Address.

Available pre-defined rules are categorised according to the application type. Click the Radio Button adjacent to the appropriate Category, and then select the required application name. Click on the Add button to move the application into the Applied Rules box. In the example shown on the previous page, 'Delta Force' has been selected from the list of Available Rules and is about to be copied to Applied Rules. In the example, this will configure the NB5 ports to use with 'Delta Force' .

To remove a rule from the Applied Rules box, select the Rule and click on the Remove Button. To save changes, click on Apply, then click on Save Settings.

Advanced Port Forwarding: Creating Custom Rules

If there is no pre-defined Port Forwarding Rule for a particular application, a User Rule can be created which defines the required Port(s), Protocol(s) and Internal Port forwarding rules.

Note than in this section, 'inside port' is indicated by the port map field and corresponds to the port number on the LAN Client. 'Outside ports' refer to the WAN port numbers and are designated by the 'port start' and 'port end' fields.

To create a custom rule you will need to know the specific port number(s) and port type [UDP or TCP] that the application requires. These will be the outside port numbers. Some applications specify a range of ports in which case you will need to know both the starting and ending port numbers in the range, which are mapped by the start port and end port fields.

The Port Map field specifies the internal port that the data will be directed to on the LAN Client.

 

When dealing with port ranges, the Internal Port (designated by the Port Map field) will be the same

 

as the first port in the range. When you simply want to forward a single port from outside (i.e. WAN

 

side) to inside (i.e. LAN side), then all three fields (Port Start, Port End and Port Map) will have the

 

same port number.
