Sorry, not possible, but it is not the fault of JBoss, or even Java. The sockets API allows you to connect to a single address only. So you have to choose one. I guess the app server could perform multiple binds on each port, but I don't know of any software that does that. It would be fairly difficult to manage, I image (don't take my word for it though, a TCP guru patiently explained this all to me and I only comprehended half of it, so I could be wrong - wouldn't be the first time. But you would be amazed at how quickly people who would otherwise ignore a post will step up and correct a misconception - I learn more stuff that way). Here are some variations on a theme: * You could run multiple copies of the app server, each bound to a different IP address. * Another option is to have Apache HTTPD manage the multiple IP addresses (not sure if you need multiple copies) and funnel all request to a single IP address for JBoss AS.
