Set Up Port Forwarding
You can use Port Forwarding to set up a computer or other network device on your home network
(LAN) to be accessible to computers or other remote network devices on the Internet. This allows you to
open specific ports behind the firewall on your LAN to set up dedicated connections between your
computer and other remote computers for online gaming or other online services. Some allowable
services are predefined under the Commonly Forwarded Ports. See Figure 39 for a list of commonly
used port numbers.
Note: ARRIS recommends that you manually configure the TCP/IP settings listed below on the computer you
are setting up for remote access. Otherwise, remote access to your computer will not be available on the
Internet.
• IP address
• Subnet mask
• Default gateway
• DNS address (at least one)
To set up Port Forwarding:
1. Click Advanced on the SBG6400 Main Menu bar.
2. Click Port Forwarding from the Advanced submenu options.

3. Click Create IPv4 to set up a specific port or range of ports for port forwarding.
Note: To map a port, you would enter the range of port numbers that you want forwarded locally and
the IP address for sending traffic to those ports. If you only want a single port specification, enter the
same port number in the start and end locations for that IP address.
