Ok,
an example may help explain where my confusion lays.
There are a bunch on online players, playing Quake3
(Lab16 8.2 IEWB).
The Quake server is sending traffic out using port
xyz.
The way I'm looking at it is that clients(players)
will send traffic to the server on port xyz, and the
server will send back traffic using source port xyz.
Usually that's the way it works on a client-server
type of connection.
The other way to look at it would be concentrating
only on the "sending traffic out using port xyz"
statement.
That may imply that xyz is a dest port.
