It is extremely common for firewalls to restrict access to certain well
known services using well known ports. For example, many ISPs no longer
allow direct connection to port 25 (SMTP) on a remote machine, and many
corporate firewalls take the approach of prohibiting anything which is not
specifically allowed. This is usually done to prevent people inside the
firewall from accessing certain "unapproved" services such as IRC or
streaming multimedia, and even telnet.
Other corporate security policies will prevent any access to the outside
network except through an HTTP proxy server, and these proxy servers will
be restricted as to what they may access. The proxy server may strip
user-agent headers, cookies, and sometimes even Javascript from viewed
pages. This is usually done to prevent outside observers, including web
site operators, from gleaning confidential company information based upon
traffic analysis.
By moving jboss-user to a web forum, you are certain to cut off access for
a large number of people, either because of security policies or increased
inconvenience.
