Port Forwarding
Port Forwarding allows for specific external ports on the AT&T Home Base to be mapped to specific ports
on a specific device on the internal network. You can have a maximum of 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
internal AT&T Home Base network.
If you select Enable, the Virtual Server Settings will appear:
IP Address: Enter the internal IP address (i.e. 192.168.1.101) that you would like traffic from a
specific 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 traffic 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 confirm your configuration.
DMZ
The DMZ, or De-Militarized Zone, is a selected internal IP address of a device that allows full access and
connectivity from outside traffic, through the firewall, to a specific internal device without being filtered or
blocked by the AT&T Home Base.
DMZ Settings: You may choose to enable or disable the DMZ setting here. DMZ is set to Disable by
default.
DMZ IP Address: Enter the internal IP address of the desired device that will be directly accessible from
outside the firewall.
