external one to internal many(but one at a time)

I have an issue where I have an internal video conferencing device that can be moved from conference

room to conference room, and each floor of the building is on a different VLAN. I can make DHCP

reservations so that I know what IP the device will get based on what VLAN it is on. Is there a way to setup an

ASA translation so that an external caller will always attach to the same internet facing IP, and the ASA

route/translate the call to the proper internal IP? Note that even though the IP relationship is one to many,

the device relationship is one to one. Does this change anything, or will the ASA not be convinced that I

know what I am doing?

Unfortunately you won't be able to use 1 external IP Address and mapping it to a few internal ip addresses because ASA will not know which internal IP to send the traffic too.
