Port Forwarding to Two Different IP's

I have two devices on my network that are nearly identical (other than IP and MAC Address) that need to be open to the same list of ports.  After creating the port forwarding rules for the first device with no problem the Firewalla sees that there is already a rule setup with the same parameters (even though it's not entirely the same, i.e. the device name/IP address are different).  Anyone know of a work around?

  You can only forward ports to one IP.

  Do you mean that you can only forward ports to one IP with the Firewalla device?  This is possible with other firewall appliances for sure.  Thanks

  You can only forward a specific port to a single device on any router I’ve seen.

  Port forward and/or NAT.  IP to IP device to device.  Now, maybe PAT to a network segment.  Thinking through this taking a vendor agnostic approach.  If I want to forward Port 23 into a device which has one set of users permissions and wanted to forward port 23 to another machine which has a different set of users, how would it know which device to send which traffic to.  If you are using a "cluster" type environment or load balancing, maybe the Firewalla could support VIP traffic?
