Figure 5-29 Port Triggering

Once the Router is configured, the operation is as follows:

1. A local host makes an outgoing connection using a destination port number defined in the

Trigger Port field.

2. The Router records this connection, opens the incoming port or ports associated with this

entry in the Port Triggering table, and associates them with the local host.

3. When necessary， the external host will be able to connect to the local host using one of the

ports defined in the Incoming Ports field.

¾ Trigger Port - The port for outgoing traffic. An outgoing connection using this port will trigger

this rule.

¾ Trigger Protocol - The protocol used for Trigger Ports, either TCP, UDP, or All (all

protocols supported by the Router).

¾ Incoming Ports Range - The port or port range used by the remote system when it

responds to the outgoing request. A response using one of these ports will be forwarded to

the PC that triggered this rule. You can input at most 5 groups of ports (or port sections).

Every group of ports must be set apart with ",". For example, 2000-2038, 2050-2051, 2085,

3010-3030.

¾ Incoming Protocol - The protocol used for Incoming Ports Range, either TCP or UDP, or

ALL (all protocols supported by the Router).

¾ Status - The status of this entry, either Enabled or Disabled.

To add a new rule, follow the steps below:

1. Click the Add New… button, the next screen will pop-up as shown in Figure 5-30.

Select a common application from the Common Applications drop-down list, then the

Trigger Port field and the Incoming Ports field will be automatically filled. If the Common

Applications do not have the application you need, enter the Trigger Port and the

Incoming Ports manually.

3. Select the protocol used for Trigger Port from the Trigger Protocol drop-down list, either

TCP, UDP, or All.

4. Select the protocol used for Incoming Ports from the Incoming Protocol drop-down list,

either TCP or UDP, or All.
