Welcome to our forums and thank-you for your support of NetworkComms.Net.
90% of the cool features possible in our network library exist because we implement our own high performance application protocol. Any clients that attempt to communicate with your NetworkComms.Net clients will not be using this protocol.
To successfully communicate with external clients you will need to use our unmanaged connection feature. For an example of this please see the unmanaged connection example included in the download bundle.
