Sun Java System Identity Synchronization for Windows 6.0 Installation and Configuration Guide

Access to the Message Queue Broker

By default, the Message Queue uses dynamic ports for all services except for its port mapper. To access the broker trough a firewall or restrict the set of hosts that can connect to the broker, the broker should use fixed ports for all services.

This can be achieved by setting the imq.service_name protocol_type .port broker configuration properties. Refer to the Sun Java System Message Queue Administration Guide for more information.
