With the old JBossMQ, we could have clients connect to the JMS topics from a different Class C network (the first set of numbers in the IP address differed from the one that JBoss was running on). With the new JBoss-Messaging we are having troubles. The JBossMessaging will accept JMS connections from machines on the same class C network, but will not accept connections from clients on a different class C network. For instance, if the JBoss is running on a machine with IP address = 10.0.1.1, then only machines with an IP address starting with 10 can connect. If I have a machine at 192.x.x.x, the client cannnot connect. I am hoping that I can enable this capability in one of the XML configuration files.
