7. When your AP receives the incoming message to destination port 113, it checks its
session table and finds an active session for port 113 associated with your computer.
The AP replaces the message’s destination IP address with your computer’s IP address
and forwards the message to your computer.
8. When you finish your chat session, your AP eventually senses a period of inactivity
in the communications. The AP then removes the session information from its session
table, and incoming traffic is no longer accepted on port numbers 33333 or 113.
