hDescription: This is for your reference of the name of the Virtual Server you will be using. You can type in your preferences.

hInternal Host IP Address: Internal Host IP Address refers to the internal computer’s IP address that you want to use. This internal computer’s IP address preferable to be manually set so you won’t have to change every time you restart the computer.

hProtocol: Protocols are the protocol type that you want to set for your internal host. For example, if you have a web server, you can set the protocol as HTTP.

hExternal Port: This is referring to the port which broadcast by your RNX-GX4. You can enter a range of the port for this setting. For example, 80~90.

hInternal Port: This is referring to the specific service TCP/UDP port of your internal host. For example, if you have a web server IP as 192.168.1.110, internal port 80, then you can set this virtual service like the picture above.

IMPORTANT:

If you set your port as 8080, you will need to change the 8080 port in the “Remote Management Port” under “Firewall” of “Security Management” to the other port. Otherwise, this may cause a conflict between the Virtual Service and Remote Management.

3.7.2 DMZ

Some programs require having multiple port connection, such as Internet Gaming programs, Video Conferencing programs, and Internet Phones. Due to the firewall limitation, these programs will not be able to work under virtual service. The purpose of a DMZ is to add an additional layer of security to your Local Area Network (LAN); an external attacker only has access to equipment in the DMZ, rather than the whole of the network.
