Once the GPON 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 GPON 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.
4.12.3 DMZ
Choose menu “Forwarding
DMZ”, and then you can view and configure DMZ host in the screen
(shown in Figure 4-87).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 GPON 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.
Figure 4-87

1. Click the Enable button.
2. Enter the IP address of a local PC that is set to be DMZ host in the DMZ Host IP Address
field.
3. Click the Save button.
