Home Networking Routers and DMZ Hosts

Finally, most home routers also support the ability to configure one internal system as a DMZ Host. In simple terms, a DMZ Host is a computer on your internal network that is completely and fully exposed to and accessible from the Internet. This option is typically used to make it simpler for a system to access multi-player online games or other services where configuring forwarding rules is confusing or cumbersome.

While configuring an internal PC on your network as a DMZ Host will immediately put an end to any port-related connectivity issues, you should also understand that you are effectively “unprotecting” this PC on your network. In other words, the router’s built-in firewall will not protect this system, leaving it susceptible to any and all of the sometimes-harsh dangers of Internet connectivity!
