4.7.4 DMZ
After a LAN computer is set to a DMZ host, this computer is not restricted when it communicates with the Internet.
For example, for some video conferences and online games, you can set computers under these applications to
DMZ hosts so that the video conferences and online games function more smoothly.
Note
When a computer is set to a DMZ host, this computer is fully exposed to the extranet and the router firewall
does act on this host any more. Hackers may use the DMZ host to attack the local network. Do not use the DMZ
host function carelessly.
It is necessary to set the DMZ host IP address to a static IP address to avoid failure of the DMZ function due to
dynamic acquisition.
Security software, antivirus software, and system firewall may affect the DMZ host function. Disable them
temporarily when using this function. When you do not use the DMZ host function, you are recommended to
cancel DMZ settings and enable firewall, security software, and antivirus software.
To add a DMZ host:
1. Log in to the device’s web UI.
2. Go to Advanced > DMZ.
3. Click Enable in the DMZ option.
4. In the DMZ IP option, enter an IP address of DMZ host, and then click Save.
