Reply To: Unable to create a TCP connection

Heya Martin,

There are a few ways of achieving this,

1. Specify the allowed IP addresses using:

HostInfo.IP.RestrictLocalAddressRanges

If you do this before calling start listening you can easily exclude adaptors that are not required.

2. The more rigorous approach is something along these lines:

//Get a list of all local endPoints using a random port
List<IPEndPoint> desiredlocalEndPoints = (from current in HostInfo.IP.FilteredLocalAddresses()
                                        select new IPEndPoint(current, 0)).ToList();

//Create a list of matching TCP listeners where we provide the listenerSSLOptions
List<ConnectionListenerBase> listeners = (from current in desiredlocalEndPoints
                                            select (ConnectionListenerBase)(new TCPConnectionListener(NetworkComms.DefaultSendReceiveOptions, 
                                                ApplicationLayerProtocolStatus.Enabled, 
                                                listenerSSLOptions))).ToList();
            
//Start listening for incoming TCP connections
Connection.StartListening(listeners, desiredlocalEndPoints, true);

Obviously only select adaptors that are required. Also see overrides to StartListening that only take a single ConnectionListenerBase. This gives you adaptor level control over listening.
