Set up Port Forwarding
Your SBG8300 firewall may be set up to block all device or application connections from the
Internet to the devices on your Wi-Fi home network. Port Forwarding allows you to open
specific ports or IP addresses on the Internet behind the firewall on your home or small
business network. It also allows for remote access to your wireless computer or other client
devices. The inbound traffic from the Internet, such as specific websites or online gaming
applications, is forwarded to the designated open ports that you set up.
Note:
ARRIS recommends that you manually configure the TCP/IP settings listed below on
the client device you are setting up for remote access. Otherwise, remote access to
your client device will not be available on the Internet.

Web Manager screen.
