Block a device from internet?
I want my surveillance camera to access my network, but not have any access to the internet, inbound or outbound. The only thing I see that looks remotely related is the "Block Services" screen, but ...
if you don't know which ports your cams use, then block all ports by using 1-65535 as port range
i have it done for a few devices and it works here. they cannot get internet access, only LAN access

I believe so. Which is why I don't enable UPnP. (That, and I have
no actual need for it. Plain-old explicit port forwarding does what I
need done. I did say "something _like_ port forwarding".)
Once, a while ago, I used Wireshark to watch a "smart socket" (Orvibo
S20) "phone home". The gizmo used a specific DNS server (located by IP
address) to find its piece of the cloud. Tough to hijack. I didn't try
to block it, but I'd expect Block Services (1-65535) to do it.
