Get remote port of a connected TcpClient

Question

For the purposes of constructing a rate limiter I need to be able to distinguish different users being routed through the same gateway. So if I have 100 clients with the same IP address I would like to tell them apart by what port they are associated with on the remote gateway/host/router.

I can get the IP easily with:

string clientIPAddress = ((IPEndPoint)tcpClient.Client.RemoteEndPoint).Address.ToString();

Is there some way similarly to get the remote port number for the client? Thanks.

Solution

var port = ((IPEndPoint)tcpClient.Client.RemoteEndPoint).Port
