Hi Brian, Yes, I started JBoss with -b option. ie, run -b 1.1.1.1 and run -b 2.2.2.2 Is there any specific changes to be made in any of the XML files to specify the NLB IP address? Other diffrence I noticed between JBoss 4.0.3 and 4.2.3 is, when I start 4.0.3 with the command 'run', it binds to localhost as well as the machine IP/Hostname. But this does not happen with 4.2.3. Any specific reason for this change? Thanks, -ashly. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4222068#...
