DMZ Host
DMZ Host allows one host in the LAN to be exposed to the Internet to use services
such as Internet gaming and video conferencing. Access to the DMZ Host from the
Internet can be restricted by using firewall access rules.
To open the DMZ Host page, click Setup > DMZ Host.
To configure a DMZ host, enter a DMZ Private IP Address and click Save.
(Port) Forwarding
Port forwarding allows public access to services on network devices on the LAN
by opening a specific port or port range for a service, such as FTP. Port triggering
opens a port range for services such as Internet gaming that use alternate ports to
communicate between the server and the LAN host.
To open the port forwarding page, click Setup > Forwarding.
Configuring Port Forwarding
When users make requests for services on your network, the device forwards
those requests to your servers based on the port forwarding parameters. Any
services not specified are denied access. For example, when port number 80
(HTTP) is forwarded to the IP address 192.168.1.2, all HTTP requests on the
interface are forwarded to 192.168.1.2. All other traffic is denied, unless
specifically allowed by another entry.
Use this function to establish a web server or FTP server. Make sure that you enter
a valid IP address. (To run an Internet server, it might be necessary to use a static
IP address.) For added security, outside users are able to communicate with the
server, but they are not allowed to connect to network devices.
