Hi,
Most routers have the ports up to port 1024 open all the time and accessible by any device.
Some list Firewalls separate from where they open ports.
Listing the Ports in the Firewall may not be enough to Open them. (However on some devices listing them to Open allows them through the Firewall)
This example pic from the Portforward.com site lists "Virtual Servers" (Port Forwarding on other devices) and a separate button for the devices Firewall.

UPnP is obviously a better option when you have multiple devices wanting to use the same ports through the router.
The D-Link in that Advanced Tab has Virtual Server and Applications (Port Triggering).
Those D-Links that have UPnP, hide it away in the Tools Tab (i.e not where other Port Opening settings are).
I know which ports to set to "Listen" for iChat when setting up Port Triggering but I have not worked it out for FaceTime.
FaceTime also has not made it on to the Lists of the Apps and Games they list for each Router set up.
