Hello,

Is there anyway to stipulate which ports clients and
servers will send on? Want to make sure that a server
application listens on a certain port and only services
clients on specific ports. As far as I know the OS of
the client offers ports to the server, so can I configure
client OS's to offer a specific port first?

OK, so I now know how to change the port that the host is
listening on. Will the host send info to the client's
address using the same port number, i.e. client:3389?
For example, a web server has port 80 reserved to listen
for client requests. When it receives a client request
it will send over port 80 to a port on the client machine
that the client OS sets up (a free port for the client to
listen on). So it sends from server:80 to client:6552.
Is that correct? If so, then how do I secure the port
the client will use to listen on?

I think it is random... A person asked this question 2 years ago and
the concensus is that the outgoing port cannot be configured...
