Q: Why do we want to configure DMZ host?

A：1. In the router set port mapping, port mapping can’t be access remotely, then you can try to open the DMZ host, if you open the DMZ host, the remote can access the port corresponding to the normal service.

   2. Don’t know the port number of some kinds of application servers  so that you can’t set port mapping, such as network cameras, some database software, etc., then you can open the DMZ host.

   3. Can’t play some games when the normal operation (e.g. StarCraft) and you can land normally, but can’t field a team, then you can open the DMZ host.

   4. Some special sites cannot open or can’t operate normally, such as certain online banking can’t be transferred, can‘t enter the verification code, etc. You can try to set the DMZ host.
