Socket c# not listen on port over internet?
- by Nguy?n Van Th?ng
Code server I have server listen on port 1450:
//Using UDP sockets
clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
EndPoint ourEP = new IPEndPoint(IPAddress.Any, 1450);
//Listen asynchronously on port 1450 for coming messages (Invite, Bye, etc).
clientSocket.Bind(ourEP);
//Receive data from any IP.
EndPoint remoteEP = (EndPoint)(new IPEndPoint(IPAddress.Any, 0));
byteData = new byte[1024];
//Receive data asynchornously.
clientSocket.BeginReceiveFrom(byteData,
0, byteData.Length,
SocketFlags.None,
ref remoteEP,
new AsyncCallback(OnReceive),
null);
but code on not open port 1450 and client connect:
otherPartyIP = new IPEndPoint(IPAddress.Parse(txtCallToIP.Text), 1450);
otherPartyEP = (EndPoint)otherPartyIP;
When i run code client and server in lan network it's ok. but run over network i check port 1450 in lan not open. tell me how open port 1450 in code server? thanks
