Port Triggering

If you configure port triggering for a certain application, you must determine a so-called trigger port and the protocol (TCP or UDP) that this port

uses. You then assign the public ports that are to be opened for the application to this trigger port. You can select known Internet services or

manually assign ports or port blocks.

DMZ Host

The demilitarized military zone (DMZ) host feature allows one

local network device to be exposed to the Internet. This function

is applicable for:

• Users who want to use a special-purpose Internet service, such

as an on-line game or video conferencing program, that is not in

the port forwarding list and for which no port range information

is available.

• Users who are not concerned with security and wish to expose

one computer to all services without restriction.

Note:

A DMZ host is not protected by the firewall and may be vulnerable

to attack. This may also put other computers in the home network at

risk. Hence, when designating a DMZ host, you must consider the

security implications and take the appropriate precautions.

You can set up a client in your local network as a DMZ host. Your

device then forwards all incoming data traffic from the Internet to this client. You can, for example, operate your own Web server on one of the

clients in your local network and make it accessible to Internet users. As the exposed host, the local client is directly visible to the Internet and

therefore particularly vulnerable to attacks (for example, hacker attacks). Enable this function only when necessary (for example, to operate a

Web server) and when other functions (for example, port forwarding) are inadequate. In this case, you should take appropriate measures for the

clients concerned.

Note:

Only one PC per public IP address can be setup as an exposed host.
