My question was misleading the way I asked, due to my own lack of knowledge. Sorry for that Bruce!
> can a SimpleServer run on port 1,000 while the SimpleClients send their requests by using Port 80?
My intention was:
Server: 1.2.3.4:1000
Client: is not tied to any port, is just sends an MyClient.OPEN('1.2.3.4', '1000').
So, the client would not be blocked by a firewall for connection to 1.2.3.4:1000 just because of the unusual port.
But, it may be blocked because the MyClient.EXE is not allowed to connect to the Internet. But other than that, it should work?
That was my intention to ask.
Thanks for your patience,
Wolfgang
