4.10.4 Verification and Testing
Use an external device to test whether the destination service can be accessed based on the external IP address
and port number.
4.10.5 Solution to a Test Failure
(1) Use a new port number and perform a test again. The test often fails on the ports blocked by firewalls of
some carriers.
(2) Enable the remote access permission on the server. The common cause is that remote access is disabled
on the server by default. As a result, the internal network access is successful but the access across different
network segments fails.
(3) Attempt to enable the DMZ service. For details, see 4.10.6 . The common cause is that configured port
information is incorrect or incomplete.
4.10.6 DMZ Configuration Steps
Mobile Phone View: Choose More > Switch to PC view > More > Advanced > Port Mapping > NAT-
DMZ.
PC View: Choose More > Advanced > Port Mapping > NAT-DMZ.
Click Enable, enter the IP address of the internal server, and click Save.
