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

1.A local host makes an outgoing connection to an external host 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.

Note:

1.When the trigger connection is released, the corresponding opened ports will be closed.

2.Each rule can only be used by one host on the LAN at a time. The trigger connection of other hosts on the LAN will be refused.

3.Incoming Ports ranges cannot overlap each other.

5.10.3DMZ

Choose menu “Advanced→Forwarding→DMZ”, and then you can view and configure DMZ host in the screen shown in Figure 5-55.The DMZ host feature allows one local host to be exposed to the Internet for a special-purpose service such as Internet gaming or videoconferencing. The router forwards packets of all services to the DMZ host. Any PC whose port is being forwarded must have its DHCP client function disabled and should have a new static IP Address assigned to it because its IP Address may be changed when using the DHCP function.
