Mysterious port forwarding

[#1]

I have a rule in my router to forward port 443 to a specific computer on my LAN.  Today I look at that rule, and it is altered.  This is the second time it has happened.  I dont know why those two external ip addresses are being added in there.  Im the only person who accesses the router, so its not that somebody in the house added it, and remote administration of my router is disabled.  There is no way to edit an existing port forwarding rule through the interface, so im not sure how these addresses are being added to my existing entry...   I tried investigating those IPs but didnt really come up with much.

 Any ideas ?

can't see the image.

BUT just a thought.  Port triggering does exactly that, and also UPNP does that as well.  

Verizon uses both for different things like Caller ID on your TV, Video on demand, widgets Remote DVR Functionality, We Remote etc....   so maybe that is what they are.
