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 37 for a list of commonly
used port numbers.
Note: It is recommended 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 SBG6700-AC Main Menu bar.
2. Click Port Forwarding from the Advanced submenu options.
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.

3. Do either of the following to set up the External IP Address:
ο Keep the IP Address set at 0.0.0.0 in the External IP Address field and then enter the port
number in the Start Port field. Repeat the same port number in the End Port field (select a
specific port from the Commonly Forwarded Ports drop-down list or see Figure 37 for the list).
This allows incoming data traffic on the specified ports from any remote IP address.
