This issue is some derivation from AS7-3040. Lets imagine starting server like this:

./standalone.sh -Djava.net.preferIPv4Stack=false -Djboss.bind.address=::1

So by default the admin/management is bound to ::ffff:127.0.0.1:9990 and ::ffff:127.0.0.1:9999, but it isn't accessible from Web WelcomePage at ::1:8080 because the URL is specified as:

<a href="/console">

and so the next request is http://[::1]:8080/console which redirect requester to http://[::1]:9990, but there isn't any console because it is here - http://[::ffff:127.0.0.1]:9990.

This is not good as it could lead to integration issues between components (X trying to connect to Y on ::1; Y listening on ::ffff:127.0.0.1).
