That's because you mounted remote jboss server and it is like your local server now. It starts on your local host. By default it uses "-b localhost" option to start and that makes it unreachable from other hosts. What you need to do are:
1. Go to Servers View and Open Server Configuration Editor (by double clicking/selecting server and pressing F3/selecting Open from context menu)
2. Change "Host name" field to 0.0.0.0 and save the editor
3. Restart server
Server will start with "-b 0.0.0.0" and that should make it accessible outside, you just have to provide right resolvable name or IP address along with port number if different from default one. Do not forget to check if your port is open on firewall.
