DMZ
Broadband Firewall Router with 4-Port Switch/VPN Endpoint
DMZ
From the DMZ Host tab you can set Port 4/DMZ to DMZ or Ethernet connection. Any user on the Internet can
access incoming or outgoing data from the DMZ host without the use of firewall protection. This feature is used
for special-purpose services such as Internet gaming and videoconferencing. Port 4 is the only port used for DMZ,
and only one computer can be in DMZ mode. Whereas Port Range Forwarding can only forward a maximum of 10
ranges of ports, DMZ hosting forwards all the ports for one PC at the same time.

switch, you can specify which PC is the DMZ host. To expose a computer with a specific IP address, enter that
computer’s IP address in this field. To get the IP address of a computer, refer to “Appendix G: Finding the MAC
