I have two jboss (4.2.1.GA) servers that are running on linux box and hosted by hosting company. They have internal IPs as 10.4.1.* and have external IPs 69.*.*.* and also have host names and then they have load balancer (hardware load balancer) in front of them, which uses 69.* IPs for load balancing. When I upgrade the servers from 4.0.5 to 4.2.1.GA and start them up with following command: $ ./run.sh -c default -b 0.0.0.0 or $ ./run.sh -c default -b 69.... or $ ./run.sh -c default -b hostname I can't connect to them by IE anymore from external. The app servers are running properly. By the way I know this topic has been addressed many times, but I am not sure why I can't solve this issue using -b 0.0.0.0 Any suggestion would be greatly appreciated View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4137251#...
