5.9.3 DMZ Setting
The DMZ host is actually a default virtual server with a lower priority than the virtual server. If the wireless
router receives a connection request from the external network, it will first look up the virtual service list
according to the service port number of the external request, and check if there is a matching mapping
entry:
•
If there is a matching entry, send the request message to the virtual server corresponding to the entry;
•
If no matching entries are found, check if there is a matching DMZ host. If the DMZ host exists, forward
all the request messages to the DMZ host, otherwise discard.
Description:
•
After the DMZ feature is enabled, the DMZ host is exposed to the Internet and the security is reduced.
•
The port number of the DMZ host should be the same as the service port number actually opened by
the DMZ.
