Register with NameServer

If the check box is selected, the messenger is registered with the controlling NameServer.

Controlling NameServer

The NameServer with which the WebSpeed Messenger registers. The WebSpeed Messenger then uses the NameServer to find a WebSpeed broker that supports the current application service. (If you did not choose to register the messenger with a NameServer, the field is dimmed and unavailable.)

Minimum NameServer client port and Maximum NameServer client port

These properties are used to specify a range of UDP ports for the messenger instance. From this range, a messenger instance can select which UDP port to use when communicating with the NameServer. To limit the range, network administrators can specify a Minimum and a Maximum value.

Specifying a range using Minimum and Maximum allows network administrators to limit the number of UDP ports needed to be open in the firewall when the NameServer client (in this case, the messenger) and the NameServer are separated by a firewall. The value for Minimum and Maximum can be zero (0) or a number between 1024 and 65535 inclusive.

The Minimum value must be less than or equal to the Maximum value. If both the Minimum and Maximum values are set to zero (0), then a random port number within the implicit fixed range is dynamically assigned. How the port is assigned depends on the platform on which the messenger instance is running. If both Minimum and Maximum values are set to the same valid port number, then this UDP port number is used when communicating with the NameServer.

The default value for both Minimum and Maximum is 0.
