We have an application that runs on Jboss 7 and when we install it on the client site we would like to tell him which ports to open in the firewall, we are not sure which one are absolutely necessary:
This is a good starting point. My suggestion would be to try the setup locally, figure out the correct ports and then pass it on to the client. Troubleshooting this setup at the client site is really not a good idea.
