Using Remote Upgrade
•This feature allows you to upgrade your Router’s firmware from a remote location. To enable Remote Upgrade, click on Enable, and then click on the Apply button. Remote Management must be activated before you can man- age the Router from a remote location.
Using MTU (Maximum Transmission Unit)
•This feature specifies the largest packet size permitted for network transmis- sion. Select Enable and enter the value desired. It is recommended that you leave this value at the 1200 to 1500 range. For most DSL users, it is recom- mended to use 1492. By default, MTU is set at 1500 when disabled.
IP Forwarding
Forwarding sets up public services on your network, such as web servers, ftp servers, or email servers. When users send this type of request to your network via the Internet, the Router will forward those requests to the appropriate PC. Before using Forwarding, the Router’s DHCP function must be disabled under the DHCP tab and the Router must be assigned a new static LAN IP address because the IP address may change when using the DHCP server.

Using Port Triggering
Port triggering allows the Router to watch outgoing data for specific port num- bers. The IP address of the computer that sends the matching data is remem- bered by the Router, so that when the requested data returns through the fire- wall, the data is pulled back to the proper computer by way of IP address and port mapping rules.
1.Enter the application name of the trigger.
2.Enter the port range used by the application.
