DMZ Configuration

A DMZ (demilitarized zone) is a computer host or small network inserted as 'neutral territory' between a private LAN and the Internet. It prevents outside users from getting direct access to LAN computers while still being able to access services hosted on the designated DMZ Computer. When using NAPT to share your internet connection, LAN computers will still be able to access the Internet when the DMZ host is enabled. Any direct communication to the WAN port of the NB5 that is not a reply to the original NAPT request is forwarded to the DMZ host.

Select Advanced>Firewall>DMZ. Check box 'Enable DMZ'.
