Once the modem 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 modem 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.

Open Ports

ranges cannot overlap each other.

4.13.3 DMZ

Choose menu “

Forwarding

→

DMZ

”, and then you can view and configure DMZ host in the screen

(shown in Figure 4-76).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 modem 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.
