Question

[Chrisz]

My program wont let me connect to anything BUT 192.*.*.* IP's or "localhost" it wont let me connect to my 'internet ip'.... Any ideas?? Btw this function below is called simply with Connect("23.236.236.23") and that ip was just.. random. :P

 

The client code:

 

 Private Function Connect(ByVal IP As String)
   On Error GoTo err
   mobjClient = New TcpClient(IP, 15200)
   DisplayText("Connected to host" & vbCrLf)

   mobjClient.GetStream.BeginRead(marData, 0, 1024, AddressOf DoRead, Nothing)

   Send("New client online")
   Connect = 1
   Exit Function

err:
   Connect = 0
 End Function

 

The server code:

 

 Private Sub DoListen()
   Try
     mobjListener = New TcpListener(15200)
     mobjListener.Start()
     Do
       'Dim x As New Client(mobjListener.AcceptSocket)
       Dim x As New Client(mobjListener.AcceptTcpClient)
       AddHandler x.Connected, AddressOf OnConnected
       AddHandler x.Disconnected, AddressOf OnDisconnected
       'AddHandler x.CharsReceived, AddressOf OnCharsReceived
       AddHandler x.LineReceived, AddressOf OnLineReceived
       mcolClients.Add(x.ID, x)
       Dim params() As Object = {"New connection"}
       Me.Invoke(New StatusInvoker(AddressOf Me.UpdateStatus), params)
     Loop Until False
   Catch
   End Try
 End Sub

 

Everything works.. apart from connecting outside my local network. That is connecting to other peoples computers running the server.... Yes they all have the .net framework and such.

What is the localhost's IP address? Can you access computers on the internet with other applications IE, ftp etc?

 

Also if you drop to a command propmpt and type

 

ipconfig /all

 

do you have entries for the default gateway?

[Chrisz]

I'm not sure about FTP, since my webhost is down.. and as for the ipconfig stuff.. i have a one default gateway entry and the rest are blank o.o

[PlausiblyDamp]

Can you ping the host you are trying to connect to? Do you know if there is a firewall between you and the other hosts?

[Chrisz]

Ping = work, <1ms too. lol.

[PlausiblyDamp]

Where is the computer located - at home / work / school etc?

Also do you know if there are any .Net security policies in place on that PC. Have a look under Administrative Tools, .Net configuration.
