DMZ Wi-Fi equipment

DMZ

— initially, DMZ is a function that allows you to create a segment on the local network with free access from the outside. From the rest of the network, this segment (it is called the DMZ — “demilitarized zone”) is separated by a firewall that allows only specially permitted external traffic to pass through. This provides additional protection against external attacks: in such cases, the DMZ suffers first of all, and access to other network resources is much more difficult for an attacker. One of the most popular ways to use this feature is to provide access to Internet services, the servers of which are physically located in the company's public local area network.

In addition, in some inexpensive routers, DMZ may mean the DMZ-host mode, which does not provide any additional protection and is used for completely different purposes (mainly to translate all ports to another network device). So the specific format of DMZ operation needs to be specified separately, especially if you are purchasing a low-cost category device.
