WCF: Net.TCP multiple bindings, same port, different IP Addresses

I've run into a problem. I'm a little new at WCF so any help would be greatly appreaciated.

Here's my code:

public static void StartHosts()
    {
        try
        {
            // Create a new host
            ServiceHost host = new ServiceHost(typeof(ServerTasks));

            List<IPAddress> ips = new List<IPAddress>(Dns.GetHostAddresses(Dns.GetHostName()));
            if (IPAddress.Loopback != null)
                ips.Add(IPAddress.Loopback);

            ips.RemoveAll(i => i.AddressFamily != AddressFamily.InterNetwork);

            foreach (var ip in ips)
            {
                string uri = string.Empty;

                // Formulate the uri for this host
                uri = string.Format(
                    "net.tcp://{0}:{1}/ServerTasks",
                    ip.ToString(),
                    ServerSettings.Instance.TCPListeningPort
                );


                // Add the endpoint binding
                host.AddServiceEndpoint(
                    typeof(ServerTasks),
                    new NetTcpBinding(SecurityMode.Transport) { TransferMode = TransferMode.Streamed },
                    uri
                );

            }



            // Add the meta data publishing
            var smb = host.Description.Behaviors.Find<ServiceMetadataBehavior>();
            if (smb == null)
                smb = new ServiceMetadataBehavior();

            smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
            host.Description.Behaviors.Add(smb);

            host.AddServiceEndpoint(
                ServiceMetadataBehavior.MexContractName,
                MetadataExchangeBindings.CreateMexTcpBinding(),
                "net.tcp://localhost/ServerTasks/mex"
            );

            // Run the host
            host.Open();
        }
        catch (Exception exc)
        {
            DebugLogger.WriteException(exc);
        }
    }

An exception is thrown on the
