Port Forwarding AirPort Extreme with ios AirPort Utility
I have the latest AirPort Extreme 802.11ac. I am attempting to set up port forwarding so I can access Plex media server from outside my home. All the relevant instructions I find for port forwarding are for older versions of the AirPort Utility app and aren't easily translated to the new app. Are there any updated instructions? Since I don't have a Mac yet only IOS app help will be useful for me.
iOS 6.1.4
