ASP.NET TcpClient intranet

Question

I'm developing an application in ASP.NET using Visual Basic, that have to connect to a Server in my private network. The application must working only into my network (in future it can work on internet, too), now I have a problem with TcpClient on ASP.NET: If I connect to the Server using an instance of IPAddress

Client = New TcpClient
Client.Connect(New IPAddress("192.168.1.12"), 6001)

the Socket try to connect to 176.64.116.11 (that's not my public IP Address...), else, if I connect to the server with a string that contains the local IP Address

Client = New TcpClient
Client.Connect("192.168.1.12", 6001)

the Socket connects succesfully but nothing responds to my command (with NetworkStream.Write and Read ) I try all of these in a Windows Application and all work succesfully.

Thanks to all (I made any mistake in English? Ahaha, sorry :D)

PS. If you post me some code in C# don't worry, I can translate it

Answer 1

TcpClient has various overloads, you can give it a string containing the ip address or an IPAddress object.

Also, use

IPAddress ipAddress = IPAddress.Parse("192.168.1.12");

IPAddress does not contain a constructor that takes a string .

As for your transmission issue; disable firewalls. Try localhost first.
