To Create A New Port Forward Rule; Adding Custom Rules To Applied Rules List - NetComm NB4 User Manual

To create a New Port Forward Rule:

On the Port Forwarding page shown in the figure above, click on the User radio button, then
on the New Button.
Rule Name: enter a name that identifies the rule; for the sake of clarity this will usually be the
name of the application. The name must be unique, must not contain spaces and cannot begin
with a number.
Protocol: can be either TCP or UDP, or both.
Port start...port end: These will be the same if you are forwarding only a single port. If there is
a range, then port start is the first number in the range, and port end will be the last number.
Port Map: this is the port number that the data should be forwarded to on the specified LAN IP
(i.e. the inside port). This is usually the same as the port start figure.
TIP: It is possible to map outside port numbers, or ranges [i.e. port start...port end] to a
different inside port numbers [port map] for reasons of security or convenience.
Click 'Apply'
The Port Rule settings defined by this process will then be displayed in a table at the bottom of
the Rule Management panel.
If you wish to add more ports to this rule, leave the text name in the Rule Name field and enter
the new port settings. Click 'Apply' and the new settings will be added to the list.

Adding Custom Rules to Applied Rules List

When you have assigned all necessary ports to the Rule and they appear in the table, click on
the Port Forwarding menu item to return to the main Port Forwarding screen.
User-created rules will be shown in the Available Rules list when the User Category radio
button is selected. You can now apply the rule(s) by selecting it and clicking Add. This will add
the rule to list of applied rules.
Click on Save Settings on the left-hand menu to make changes permanent.
