nginx port 80 firewall hack thing

README.md

All assumes you're running nginx on port 8080. Change ports to suit your needs.

1. Copy ipfw.plist into /Library/LaunchDaemons/ipfw.plist
2. Copy ipfw.conf into /etc/ipfw.conf

If you want this to work straight away, you may need to run:

$ sudo launchctl load /Library/LaunchDaemons/ipfw.plist

Also, maybe restart a couple of times. This has worked for me but might do nothing for you :)

ipfw.conf

# Forward port 80 to 8080
add fwd 127.0.0.1,8080 tcp from any to me dst-port 80 in
