On a CLIENT you cannot make more than 32k connections to the same IP/Port combination. It's impossible. On a SERVER you can have trillions of incoming connections, BUT, they MUST come from different IP addresses up to a maximum of 32k per IP address. Think of the table like this: 1) Local IP 2) LocalPort 3) Remote IP 4) RemotePort 1 is usually fixed unless you listen on more than one IP address. 2 is usually fixed (e.g. port 80 for http) 3 varies in IPv4 up to 4 billion-ish addresses 4 varies and is generally randomly chosen by the OS, but is in a fixed range up to 32k If you fix 1 2 and 3 then you can only have 32k connections. But if you vary 3 then your number is limitless (practically). Does that help?
