4.7.2 Port Triggering

Some applications require multiple connections, like Internet games, video conferencing, Internet calling and so on. These applications cannot work with a pure NAT router. Port Triggering is used for some of these applications that can work with an NAT router. You can set up Port Triggering on this page shown in

Figure 4-29:

Figure 4-29 Port Triggering

Once configured, 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 section). 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).

- 41 -

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

4.7.3 DMZ

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. DMZ host forwards all the ports at the same time. 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 change when using the DHCP function. You can set up DMZ host on this page shown in Figure 4-31:

Figure 4-31 DMZ

To assign a computer or server to be a DMZ server:

1. Click the Enable radio button

2. Enter the local host IP Address in the DMZ Host IP Address field

3. Click the Save button.

Note:
