Answer 1

Sad hack around is simply to block off that port to the outside world. Below you're allowing local access, but banning everyone else. This will keep people from bypassing your proxy (i.e. getting around HTTPS if you terminate there).

iptables -A INPUT -s 127.0.0.1/32 -p tcp -m tcp --dport 9000 -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 9000 -j DROP

If you bork your iptables settings, just run the following to reset them. PS, don't screw with port 22 if your on a remote VM. ;)

iptables -F

You need to use "localhost" as the http.address target.

play start -Dhttp.address=localhost

For some reason, specifying 127.0.0.1 as http.address is causing it to bind to 0.0.0.0, which seems like a bug to me. Using localhost, however, works.
