NetComm N300 manual Port Forwarding, Dmz

Port Forwarding

This page allows you to configure port forwarding rules to allow remote users to access services such as Web or FTP on your local computers. This allows you to redirect a particular port number (from the Internet/WAN port) to a particular LAN IP address.

Name	Description
Virtual Server Settings:	Enable/Disable port forwarding
IP Address:	The LAN IP address that the public port number packet will be sent to
Port Range:	The public port numbers to be sent to the specific LAN IP address
Protocol:	Select the port number protocol type (TCP, UDP or both). If you are unsure, then
	leave it as the default “TCP&UDP” setting
Comment:	Add a comment to identify the rule (optional)

DMZ

If you have a client PC that cannot run an Internet application (e.g. Games) properly from behind the NAT firewall, then you can open up the firewall restrictions to allow unrestricted two-way Internet access by defining a DMZ Host.

The DMZ function allows you to re-direct all packets going to your WAN port IP address, to a particular IP address in your LAN. The difference between the virtual server and the DMZ function is that the virtual server re-directs a particular service/Internet application (e.g. FTP, websites) to a particular LAN client/server, whereas DMZ re-directs all packets (regardless of services) going to your WAN IP address to a particular LAN client/server.

Name	Description
DMZ Settings:	Enable/disable DMZ.
DMZ IP Address:	Fill-in the IP address of a particular host in your LAN Network that
	will receive all the packets originally going to the WAN port/Public IP
	address of your 3G Router.

Click Apply to save the above configurations.
