I'm in the process of moving from an old Slackware install where I did *everything* by hand, including adding reverse proxy requests to be re-directed to an internal server.
I can't seem to figure out how to do this through ISPConfig3.
What I required, is a subdomain based redirect, ie:
webmail.domain.com -> http://192.168.0.3/webmail
How can I do this in ISPConfig3?
