IP SPECIFIC NAT - WILL THIS WORK?

[teletubby5e]

HELLO,
I HAVE ONLY ONE PUBLIC IP ADDRESS FOR THE WATCHGUARD. I WANT TO GIVE TELNET ACCESS TO A SPECIFIC DEVICE 'A' WITH PRIVATE IP ADDRESS TO CONTRACTOR 'A', WHO I KNOW WILL BE COMING IN FROM A SPECIFIC CLASS C NETWORK. BUT NOT GIVE HIM MUVPN CLIENT OR ACCESS TO ANYTHING ELSE. LIKEWISE WITH DIFFERENT CONTRACTORS. CONTRACTOR 'B' COULD TELNET TO SAME SINGLE PUBLIC IP ADDRESS FROM A DIFFERENT NETWORK BUT HIT A DIFFERENT DEVICE 'B'. AM I JUST NOT CALLING IT THE RIGHT THING?

THANKS FOR YOUR HELP.

JEFF
