Thanks for the advice! Actually, I think my problem was in trying to set JBoss's IP, when all I wanted to do was set Tomcat's listening IPs. If I keep running jboss's run.sh with the system's IP for -b, but edit the jboss-web.deployment/server.xml file so that the elements don't specify an IP, then Tomcat will listen on all ports, but JBoss's clustering will run as normal.
