Block ioT access to internet but, allow NTP time synchronization

I have some home security cameras (Reolink, Amcrest and Foscam). I'd like to block them from having general access to the internet while still allowing them to auto-update their time settings from an NTP server. Anyone know how to do that?

Re: Block ioT access to internet but, allow NTP time synchronization

Orbi routers have a feature called Block Services (on the Advanced Tab, Security Menu).

Network Time Protocol (NTP) uses UDP port 123.  Three rules would block a camera from everything else:

  1. Block TCP ports 1-65535
  2. Block UDP ports 1-122
  3. Block UDP ports 124-65535

It would be really convenient if all of the cameras have consecutive IP addresses.
