Networking – What’s DMZ used for in a home wireless router


As far as I understand, by using DMZ you expose all of the host computer's ports to the Internet. What's that good for?

Best Answer

The DMZ is good if you want to run a home server that can be accessed from outside of your home network (ie web server, ssh, vnc or other remote access protocol). Typically you would want to run a firewall on the server machine to make sure only the ports that are specifically wanted are allowed access from public computers.

An alternative to using the DMZ is to setup port forwarding. With port forwarding you can allow only specific ports through your router and you can also specify some ports to go to different machines if you have multiple servers running behind your router.
