This project can be used to create a Radius server in for example a Windows Service.
Packets are handled in multiple threads without running several instances. This can be useful when packet handlers do something slow, like lookups from external dependencies.
Pluggable packet handlers for different remote IPs.
Conditionally compliant with RFCs

See https://github.com/vforteli/RadiusServerService/tree/Base for an example implementation
Create a project or appropriate type and add a reference to Flexinets.Radius.RadiusServer
var path = Path.GetDirectoryName(AppDomain.CurrentDomain.BaseDirectory) + "/Content/radius.dictionary";
var dictionary = new RadiusDictionary(path, NullLogger<RadiusDictionary>.Instance);
var radiusPacketParser = new RadiusPacketParser(NullLogger<RadiusPacketParser>.Instance, dictionary);
var packetHandler = new TestPacketHandler();
var repository = new PacketHandlerRepository();
repository.AddPacketHandler(IPAddress.Any, packetHandler, "secret");
var server = new RadiusServer(
new UdpClientFactory(),
new IPEndPoint(IPAddress.Any, 1812),
radiusPacketParser,
RadiusServerType.Authentication,
repository,
NullLogger<RadiusServer>.Instance);
server.Start();
The packet handler should implement IPacketHandler
