Hi,
I believe, that original question was about situation
where You have only one valid IP from ISP and use NAT overload.
Is it possible on Cisco router to route, to NAT, whatever,
based on destination port (application) ?
Let say You have one external IP (assigned by ISP) - "A" and two
internal devices with RFC1918 IPs "B" & "C".
B & C - are inside locals, A - inside global. NAT overload
And we want to telnet from outside to "B" and VNC to "C" ?
I think that soultion is here (I didn't try this):

Configure static (NAT) translations back to the internal ip address.
