Test the tcp connection between client and server
client send from and receive to port is ephemeral
server receive to and send from port is well known
Server listens on ist well know receive to and send from port
So incoming to server.
Source address is client host and client ephemeral port
Destination address is server host and server well known port
Each accept socket on server is a different duple of client source, server dest
all the dest are the same but each source is differenct so can route
based on the source.
Server routes incoming packets to accept socket port. The routing uses
the clients send from ephemeral port to do the routing to the
correct accept socket. All the accept sockets have the same local
port but a different remote IP host .
The servers accept socket port is the well known port so still receives to
and sends from its well know port.
The server sends to and receives from the clients ephemeral port number.
