    3.5.1. Virtual Server This product’s NAT firewall filters out unrecognized packets to protect your Intranet, so all hosts behind this product are invisible to the outside world. If you wish, you can make some of them accessible by enabling the Virtual Server Mapping. A virtual server is defined as a Service Port, and all requests to this port will be redirected to the computer specified by the Server IP.

  • Page 23: Special Ap

    Some applications require multiple connections, like Internet games, Video conferencing, Internet telephony, etc. Because of the firewall function, these applications cannot work with a pure NAT router. The Special Applications feature allows some of these applications to work with this product. If the mechanism of Special Applications fails to make an application work, try setting your computer as the DMZ host instead.

  • Page 24: Miscellaneous Items

    3.5.3. Miscellaneous Items IP Address of DMZ Host DMZ (DeMilitarized Zone) Host is a host without the protection of firewall. It allows a computer to be exposed to unrestricted 2-way communication for Internet games, Video conferencing, Internet telephony and other special applications. NOTE: This feature should be used only when needed.
