To Enable Broker Connections Through a Firewall

1. Assign a static port address to the connection service you wish to use.

   To bypass the Port Mapper and assign a static port number directly to a connection service, set the broker configuration property imq.serviceName.protocolType.port, where serviceName is the name of the connection service and protocolType is its protocol type (see Table 9–8). As with all broker configuration properties, you can specify this property either in the broker's instance configuration file or from the command line when starting the broker. For example, to assign port number 10234 to the jms connection service, either include the line

      imq.jms.tcp.port=10234
   

   in the configuration file or start the broker with the command

      imqbrokerd  -name brokerName  -Dimq.jms.tcp.port=10234
   

   where brokerName is the name of the broker to be started.

2. Configure the firewall to allow connections to the port number you assigned to the connection service.

   You must also allow connections through the firewall to Message Queue's Port Mapper port (normally 7676, unless you have reassigned it to some other port). In the example above, for instance, you would need to open the firewall for ports 10234 and 7676.
