ATA Routing Field Reference Application page A • "System Reserved Ports Range section," on page 114 Router tab > Application page > Port Forwarding Settings section This feature allows you to set up specialized Internet applications that require port forwarding on a range of ports. Enable Service Name Starting Port Ending Port Protocol Server IP Address Options are Yes or No. Any name to call the port forwarding starting port. The starting port of the port range you wish to forward. The ending port of the port range you wish to forward. The protocol that is used: TCP, UDP, or BOTH. The LAN address of the computer to receive port forwarding. Router tab > Application page > DMZ Settings section The DMZ feature allows one network computer to be exposed to the Internet for use of a special-purpose service such as Internet gaming or video conferencing. DMZ hosting forwards all the ports at the same time to one PC. The Port Forwarding feature is more secure because it only opens the ports you want to have opened, while DMZ hosting opens all the ports of one computer, exposing the computer to the Internet. Enable DMZ DMZ Host IP Address Any PC whose port is forwarded must have its DHCP client function disabled and should have a new static IP address assigned to it because its address may change when using the DHCP function. To expose one PC, select Yes. The default is No. Specify the host computer's IP address. Cisco Small Business ATA Administration Guide 113
