Hello jeremy30thz. Welcome to the Apple Discussions!

Note: The PS3 requires the following ports opened to establish either a Type 1 or Type 2 connection with a router:
TCP: 80, 443, 5223
UDP: 5223, 3478, 3479, 3658

(ref: How to get a Type 2 (Open) NAT on your PS3)

AEBSn - Port Mapping Setup
To setup port mapping on an 802.11n AirPort Extreme Base Station (AEBSn), either connect to the AEBSn's wireless network or temporarily connect directly, using an Ethernet cable, to one of the LAN port of the AEBSn, and then use the AirPort Utility, in Manual Setup, to make these settings:

1. Reserve a DHCP-provided IP address for the PS3.
Internet > DHCP tab
o On the DHCP tab, click the "+" (Add) button to enter DHCP Reservations.
o Description: <enter the desired description of the host device>
o Reserve address by: MAC Address
o Click Continue.
o MAC Address: <enter the MAC hardware address of the PS3>
o IPv4 Address: <enter the desired IP address>
o Click Done.

2. Setup Port Mapping on the AEBSn.
Advanced > Port Mapping tab
o Click the "+" (Add) button
o Public UDP Port(s): <enter the appropriate UDP port values>
o Public TCP Port(s): <enter the appropriate TCP port values>
o Private IP Address: <enter the DHCP-reserved IP address that you established earlier for the PS3>
o Private UDP Port(s): <enter the same as Public UDP Ports>
