Port Forwarding to Multiple Machines

Port forwarding on the AEBS seems to be tied to a specific IP address on the LAN. I really want to be able to access these ports from any computer on the LAN, but have not been able to figure out how to do this. AirPort Utility does not allow me to specify multiple IP addresses when I open the ports, or allow multiple instances of a port mapping for different IP addresses.

Is there a way I can open these ports for all machines on the LAN?

Mac OS X (10.5.7)

The AirPort Utility and your AEBS are working as designed. You can map a single or multiple ports to a single IP address, but you cannot map the same port to multiple IP addresses.

In order to allow access from the internet to your internal network through your router you must have an external public ip address (these are provided by your ISP (you say you have 5). If your claim is true, then you do not need to map ports. You simply need to map those public ip addresses to the computers you wish to see publicly. Port mapping is needed when you have multiple computers using a single public ip address. Port mapping is necessary to connect outside users to the appropriate computer.
