Hi. Thanks for your response. Would using the real IP address of the DC allow me to access the management console remotely? I was under the impression that using 0.0.0.0 was the only way for this to work. I do have a subscription and can open a case if necessary. Although I figured that as a new JBoss admin, this is probably a quick and easy answer for the veterans.
Wolf-Dieter, your suggestion was correct! I can successfully use the actual IP address of the machine where the DC lives and all connections-- local HC connection, remote HC connection, management console connection from remote hosts- all worked just fine. I did try that once in my troubleshooting, but determined after the fact that my local firewall was culprit as to why remote connections were not working.
