I have exactly the same question but for domain mode, or in general how do you pass startup parameters when you install Wildfly as a Windows service? Have you found a solution yet?
For us the solution was to set the environment variable JAVA_OPTS, like:
Our service runs on a dedicated virtual system, so there is no reason not to set system envorinment variables.
Otherwise one might prefer to change the start script.
Thank's for you answer! I guess I will also do it like this and set jboss.bind.address option in the domain.conf.bat file.
