Using Open.Nat.ConsoleTest project

The Open.Nat solution includes the Open.Nat.ConsoleTest project that can be used for Troubleshooting. Just download the code and run it.

Your IP: 181.110.171.21
Added mapping: 181.110.171.21:1700 -> 127.0.0.1:1600Mapping List

Enabling tracing in your project

Open.Nat provides its own TraceSource in order to enable applications to trace the execution of the library's code and find issues. To enable the tracing you can add the following two lines of code:

NatUtility.TraceSource.Switch.Level = SourceLevels.Verbose;
NatUtility.TraceSource.Listeners.Add(new ConsoleListener());

The first line specifies the tracing level to use and the levels used by Open.Nat are: Verbose, Error, Warning and Information. You should set it to Information first and switch to Verbose if erros occur. The scond line add a trace listener and you can choose the one that is better for you, some of the available listeners are:

Code Example

Here you can see a code snippet used to get the external IP Address.

NatUtility.TraceSource.Switch.Level = SourceLevels.Information;
NatUtility.TraceSource.Listeners.Add(new ColorConsoleListener());

NatUtility.DeviceFound += (sender, args) => {
    Console.WriteLine("It got it!!");
    var ip = await device.GetExternalIPAsync();
    Console.WriteLine("The external IP Address is: " + ip);
};

NatUtility.Initialize();
NatUtility.StartDiscovery();

And here, the tracing output:
