Typo in TransparentProxyServer ctor

[zbalkan]

The TransparentProxyServer constructor does not validate the parameter but the field which always have the default value, invalidating the guard clauses.

TechnitiumLibrary/TechnitiumLibrary.Net/Proxy/TransparentProxyServer.cs

Lines 64 to 73 in a11ca1e

	public TransparentProxyServer(IPEndPoint localEP, IProxyServerConnectionManager connectionManager = null, TransparentProxyServerMethod method = TransparentProxyServerMethod.DNAT, int backlog = 10)
	{
	if (_method != TransparentProxyServerMethod.Tunnel)
	{
	if (Environment.OSVersion.Platform != PlatformID.Unix)
	throw new NotSupportedException("Only Unix/Linux is supported.");
	if ((method == TransparentProxyServerMethod.DNAT) && (localEP.AddressFamily != AddressFamily.InterNetwork))
	throw new NotSupportedException("Only IPv4 is supported with DNAT.");
