Consider a MSN Gaming Zone server that is accessed by the LAN Client using TCP protocol on port 47624.
The gaming server responds by connecting the user using TCP on port 2400 when starting gaming sessions.
In such a case you must use dynamic port forwarding, since this scenario confl icts with the following default
fi rewall settings:
• The fi rewall blocks inbound traffi c by default.
• The server replies to device´s IP, and the connection is not sent back to the Client, since it is not part of a
session.
•
In order to solve this you need to defi ne a dynamic port forwarding rule, which allows inbound traffi c on TCP
port 2400, only after a LAN Client generated traffi c to TCP port 47624. This will result in accepting the inbound
traffi c from the gaming server, and sending it back to the LAN Client which originated the outgoing traffi c to
TCP port 47624.
