Port Forwarding - AT&T Home Base User Manual

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.
