Firewall: Port Forwarding
Port Forwarding allows for specic external ports on the AT&T Wireless Internet device
to be mapped to specic ports on a specic device on the internal network. You can
have a maximum of ten (10) Port Forwarding/Virtual Server rules in the system.
You can Enable or Disable Port Forwarding to allow certain devices to act as virtual
servers within the AT&T Wireless Internet device’s internal network.
If you select Enable, the Virtual Server Settings will appear:
• IP Address: Enter the internal IP address (e.g., 192.168.1.101) that you would like
trac from a specic external port directed to internally.
• Port Range: Enter the starting and ending port numbers that will be directed
to the internal device.
• Protocol: You may pick TCP, UDP, or TCP+UDP trac types to be directed.
• Comment: Enter a comment or label to be saved with this custom port
forwarding rule.
Be sure to click Apply to conrm your conguration.
