3.11.4 Configuring a Special Application* (not supported
Sunrise service)
Note: configuration and potential issues related to Special Application are not part of
Sunrise Customer Services support
The Sunrise Internet Box 5G supports the function to use a special application to
configure dynamic port forwarding. Certain applications in the local area network (LAN)
must use a specified port of the firewall to access remote applications. To set up a
Transmission Control Protocol and User Datagram Protocol (TCP/UDP) connection
between an application in the LAN and a remote application, the firewall uses this port
forwarding function to open the required port.

Example of the Configuration of a Special Application
A client in the LAN uses TCP to access the MSN game server through port 47624.
When the game starts, the game server uses TCP and port 2400 to set up a
connection to the client that tries to access the server. In this case, you must 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
Sunrise Internet Box 5G but cannot send the request to the LAN client that tries
to access the game server, because the IP addresses of clients are not open to
external devices.
To solve this problem, you must define a set of port forwarding rules. When the client
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 client that sends data to TCP port 47624.
