Firewall - MAC/IP/Port Filtering
Custom Applications: This feature allows you to define your own applications.
Once defined, these applications can be enabled and disabled the same way as
pre-defined applications. To define an application, you need to know the ports and
protocol (TCP, UDP) used by the application for outgoing traffic. To start, click the
Add Custom Application button, then provide the following data:
MAC Address: A network identifier unique to each device's hardware.
Destination IP Address: The internal IP address where traffic will be
filtered to.
Source IP Address: The source IP address that traffic will be filtered from.
Protocol: You can select from None/TCP/UDP/ICMP as the traffic type you
would like to filter.
Destination Port Range: The range of ports that traffic will be filtered to.
Enter the beginning and end of the port range for each application.
– For a single port, enter the port number in both fields.
– For a port range, enter the beginning of the range in the first field and the
end of the range in the second field.
Source Port Range: The range of ports that traffic will be filtered from.
Action: Selecting Drop or Accept will determine if the rule will allow or block
traffic based on the criteria specified.
Comment: Here you will need to add a name or description to the rule in
order to click "Apply" to save and implement the rule.

Device Configuration
Firewall - 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.
