The most likely cause is the ports that FaceTime uses for video that are above the 1024 threshold in your router.
Basically there are 65535 ports in all. (think of them like TV channels).
The first 1024 are always open on most routers.
Web Browsing is on port 80 with some secure stuff on port 443.
Mail uses many ports, 25 is a common STMP (outgoing) server. 110, 565, 568, 998 are common POP server but many are used.
FTP used to upload web pages is on port 21 and 22.
Some app and games use port above this threshold and you have to specifically say to have them open.
There and many methods of doing this.
UPnP allows many devices to use the same ports.
It is generally a simple On/Off setting.
