7. When your router 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 router 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 router eventually senses a period of inactivity
in the communications. The router then removes the session information from its
session table, and incoming traffic is no longer accepted on port numbers 33333 or
113.
