attacks from viruses and hackers.

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 feature allows inbound traffic from the Internet to specific ports behind the firewall on your

LAN. You 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 38).

To set up Port Forwarding:

1.

Log in to the SBR-AC1750 Web Manager and then click Firewall on the SBR-AC1750 Main

Menu bar.

2.

Click Port Forwarding from the Firewall submenu options.

Set Up the DMZ Host

WARNING!

The gaming DMZ host is not protected by the SBR-AC1750 router firewall. It is

exposed to the Internet and thus vulnerable to attacks or hacking from any computer on

the Internet. Consider carefully before configuring a device to be in the DMZ.

You can configure one computer on your home network to be the DMZ. That computer will

operate outside of the SBR-AC1750 firewall and allow remote access from the Internet to your

computer, gaming device, or other IP-enabled device. The DMZ feature will only allow outside

users to have direct access to the designated DMZ device and not your home network.
