A couple things come to mind:
1. Diagnose port mapping. From the computer you are trying to use for the VNC client (and failing to connect to your wireless OSX/VNC box), try to telnet to port 5901 at the AirPort Base Station's IP address. If you don't get a connection and some odd characters, the port mapping isn't working. In terminal on your OSX/wireless machine, telnet to localhost port 5901 to see what it should look like. If you get a connection, research whether VNC server can be accessed via address translation through firewalls, maybe it just doesn't work. I only use the VNC client on my wireless/OSX machine to access a VNC server on the wired network, so I haven't tried what I think you are trying.
2. Get rid of port mapping. You only need it if you are restricted to a single IP address (the Base Station's) on your wired network. If you have a local network with available IPs, just reconfigure the Base Station to do bridging only and VNC directly to your wireless/OS X box without mapping.
