configure dynamic port forwarding, because the game conflicts with the following
default firewall rules:

The firewall blocks external data input.

The game server can send a connection request to the external IP address of the
Smart Hub but cannot send the request to the LAN device that tries to access the
game server, because the IP addresses of devices are not open to external
devices.
To solve this problem, you must define a set of port forwarding rules. When the device
in the LAN sends data to TCP port 47624, the rules allow data input from TCP port
2400. Then data from the game server can be received from and transmitted to the
LAN device that sends data to TCP port 47624.

8.7 Configuring the DMZ
If external users cannot access certain network services provided by the local area
network (LAN), use the DMZ function provided by the Smart Hub to set the device
that provides the required network services as the DMZ host; external users can then
access these services properly. DMZ is an acronym for the demilitarized zone in
networks.
Prerequisites
DMZ users are not protected by the firewall and may be easily attacked. In addition,
the security of other users in the LAN is compromised.
Procedure
Step 1 Choose Settings > Security > DMZ Settings.
Step 2 Select:

Enable: to enable the DMZ function.

Disable: to disable the DMZ function.
Step 3 In DMZ IP address, enter the IP address of the device to be set as the DMZ host.
One device can be set as the DMZ host at a time.
Step 4 Click Apply.
