Did you use the -b option on the command line when starting JBoss AS? See:
https://community.jboss.org/wiki/JBoss42FAQ
Are you running on Linux? If so, is your /etc/hosts file configured correctly? See this discussion:
http://community.jboss.org/thread/120995
Finally, based on this part of the error message: "sslsocket://0.0.0.0:3843/", I hope that you did not use 0.0.0.0 in your remote client's configuration, that will not work as there is no such IP address.
