Automatic Port Forward w/ Open.NAT

[Deathreus]

Not everyone is tech savvy enough to go through the process of opening ports to the public when they just want to quick-start a server for friends, this can easily be solved with the NuGet package Open.NAT

A quick and dirty mockup of the process is as follows:

var discoverer = new NatDiscoverer();
try
{
    var device = await discoverer.DiscoverDeviceAsync();
    var mappings = await device.GetAllMappingsAsync();

    if (!mappings.Any(m => m.Protocol == Protocol.Udp && m.PrivatePort == _serverData.ServerPort && m.PublicPort == _serverData.ServerPort))
    {
        var mapping = new Mapping(Protocol.Udp, _serverData.ServerPort, _serverData.ServerPort, _serverData.ServerName);
        await device.CreatePortMapAsync(mapping);
    }
}
catch
{
}

feel free to change as needed

thanks for that, but I believe WindowsFirewall.cs already did this feature I think.

Removing my forwarding shows otherwise
