Ok... so here's what I've been told. If you start JBoss with the --host=x, or -b x, where x is an ip, localhost, or machine name, it will ONLY bind to that one address. If you do not include those flags, it will bind to all available addresses. (This is clearly what you want) The default behavior in the IDE is to bind to the host declared in the wizard used to create the server. ** TO CHANGE THIS ** for one server, you have to change it's command line arguments as follows: In the server or JBoss Servers view, double click the server to open its editor. Select the "Open Launch Configuration" hyperlink. Go to the start arg tabs and remove the "--host=xyz" portion. That should fix your issue.
