DMZ
Some applications experience problems when working behind a firewall. To solve this problem you can put computers outside
of the firewall via the router's DMZ (demilitarized zone) feature. The DMZ feature disables the NAT firewall and allows all data
to pass through all ports to this computer.
Follow the instructions below to enable the DMZ feature.
1. Click to select Enable DMZ Host.
2. Type the IP address of the computer that will run the gaming application in the DMZ IP Address field.
3. Click the Apply button to apply the new settings.
Port Forwarding Settings
Port forwarding allows you to configure your router to accept unsolicited data through a specific port. The ports and protocol
type (TCP, UDP, or both) will depend on what gaming service you are using.
NOTE: This information should be available from your gaming service or your the documentation that came with your game.
To enable Port Forwarding, perform the following steps:
1. Click the Add button. The Gaming: Add a Record window appears.
2. Type the desired name or description in the Game Description field. This cannot be more than 31 characters in length.
3. Type the IP address of the device (for example, desktop computer) for gaming in the Computer IP for gaming field.
4. Select a transport layer protocol from the Protocol Type list. The options listed here are TCP (Transmission Control
Protocol), UDP (User Datagram Protocol), and both.
