Port Range Forwarding

The Port Forwarding screen sets up public services on your network, such as web servers, ftp servers, e-mail

servers, or other specialized Internet applications. (Specialized Internet applications are any applications that use

Internet access to perform functions such as videoconferencing or online gaming. Some Internet applications

may not require any forwarding.) (See Figure 5-27.)

When users send this type of request to your network via the Internet, the Gateway will forward those requests to

the appropriate computer. Any computer whose port is being forwarded should have its DHCP client function

disabled and should have a new static IP address assigned to it because its IP address may change when using

the DHCP function.

•

Application. Enter the name you wish to give each application.

•

Start and End. Enter the starting and ending numbers of the port you wish to forward.

•

TCP UDP. Select the type of protocol you wish to use for each application:

TCP

,

UDP

, or

Both

.

•

IP Address. Enter the IP Address and Click

Enabled

.

Port Triggering

Port Triggering is used for special applications that can request a port to be opened on demand. For this feature,

the Gateway will watch outgoing data for specific port numbers. (See Figure 5-28.) The Gateway will remember

the IP address of the computer that sends a transmission requesting data, so that when the requested data

returns through the Gateway, the data is pulled back to the proper computer by way of IP address and port

mapping rules.

•

Application. Enter the name you wish to give each application.

•

Start Port and End Port. Enter the starting and ending Outgoing Triggered Range numbers and the Incoming

Forwarded Range numbers of the port you wish to forward.

DMZ

The DMZ screen (see Figure 5-29) allows one local user to be exposed to the Internet for use of a special-purpose

service such as Internet gaming and videoconferencing through DMZ Hosting. DMZ hosting forwards all the ports

for one computer at the same time, which differs from Port Range Forwarding, which can only forward a

maximum of 10 ranges of ports.

•

DMZ Hosting. This feature allows one local user to be exposed to the Internet for use of a special-purpose

service such as Internet gaming and videoconferencing. To use this feature, select

Enabled

. To disable DMZ ,

select

Disabled

•

DMZ Host IP Address. To expose one computer, enter the computer’s IP address. To get the IP address of a

computer, refer to “Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter.”
