[RESOLVED] Self Test TCP Client Server Connection

[Pradeep1210]

Hi,

I made a server app and a client app from the post in Atheist's signature (TCP client/server connection ).
Then I tried to run both on my machine, as a self test.
However the results were not as expected.

The server runs fine.

The client runs fine when I put IP Address 127.0.0.1, but errors out when I put my actual internet IP address.

Private client As System.Net.Sockets.TcpClient
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    client = New System.Net.Sockets.TcpClient("122.162.75.237", 43001)  '<-- Error: SocketException - No connection could be made because the target machine actively refused it 122.162.75.237:43001
    client.GetStream.BeginRead(readBuffer, 0, BYTES_TO_READ, AddressOf doRead, Nothing)
End Sub

The IP address I put there is what I can see myself from many sites like www.whatismyip.com etc.
I also tried a ping on that address and it returns fine.

What could be the reason?
