I got an unexpected message from my Fritz 7490 a couple of days ago... actually Friday 7th! Geeze is the the first time I've been able to do something it??

It said "The TCP port for Internet access to your FRITZ!Box via HTTPS was changed by 472 to 469". Now, there was no reason for this to change- I was on the bus on the way home, my wife was probably cooking the kids' dinner.

Did anyone else get this? Was it a "managed activity" from 2degrees? Should I be worried? There does not appear to be any unexpected traffic on the router, and I don't actually have Internet Access to the device turned on.

Anyone? TIA!

Edit: I've changed it to something else above 1024 so do I need to change it back?
