Port Forwarding Past Airport Firewall

I'm trying to forward ports for an application of mine called "Steam" (it's for online gaming).

I have pulled up the AirPort Utility, and I see where I can put a list of ports (screenshot below)

The instructions from steam are:

Your network must be configured to allow Steam access to the following ports (in order from highest to lowest priority for QoS users):

Steam Client

UDP 27000 to 27015 inclusive (Game client traffic)
UDP 27015 to 27030 inclusive (Typically Matchmaking and HLTV)
TCP 27014 to 27050 inclusive (Steam downloads)
UDP 4380

Dedicated or Listen Servers

TCP 27015 (SRCDS Rcon port)

Steamworks P2P Networking and Steam Voice Chat

UDP 3478 (Outbound)
UDP 4379 (Outbound)
UDP 4380 (Outbound)

Additional Ports for Call of Duty: Modern Warfare 2 Multiplayer

UDP 1500 (outbound)
UDP 3005 (outbound)
UDP 3101 (outbound)
UDP 28960

I've done what I thought would work, but still nothing. Help?

The fundamental issue here maybe that Port Forwarding/Mapping, on the AirPort routers, is for inbound traffic only. All ports are "open" going outbound. The other thing to take into consideration is firewall ports on the game host computer or server itself. These too would need to be open as required for each game.

What you configured, per the image, is for port mapping inbound.
