Hello You all,
I have copy and paste a code snippet example of a N+ server and change it a bit for own use.

We use portForwarding in the router.

When I execute this code and use the browser with a intern address 192.168.1.55:66777/ledon then the code works perfect.

But when I execute the code and use the browser with my extern ip address [IPADDRESS]:66777/ledon then I must 2 times enter the browser, the code will then execute but after I get a error exception in the code: Using socketConnection As Socket = socketServer.Accept()

When I change .Poll(-1, ... In .Poll(50000,... then it works perfect.

Now my question:
I do not know why I get an error and what's the difference between, Is there any difference in handling local and external calls?
Thank You Ellen.

Using socketServer = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)    
   socketServer.Bind(New IPEndPoint(IPAddress.Any, intPort))
   socketServer.Listen(1)

   While True
 
     Try

         Using socketConnection As Socket = socketServer.Accept()

            If socketConnection.Poll(-1, SelectMode.SelectRead) Then

Hello Supra, thank you for the link. I had already read the MSDN description of Poll. But can you answer my question why Poll(-1 methode do not work and generates an error when the N+ has a external request? Is it maybe a anomalistic behavior?

Sorry tag code doesn't work probably

try this:

Using socketServer = New Socket(AddressFamily.InterNetwork, SocketType.SDgram, ProtocolType.Udp)

It's a long shot, but try change socketServer.Listen(1); to a higher number..
