So I have devices that need internet but only to specific sites. Problem is those sites are on cloud servers and arent using a specific IP range.
Example - Xerox printer need to get to xerox for updates but no where else on the internet. Xerox is running it's servers on AWS and do not have a specific IP or IP range..
So how would you go about blocking ALL internet traffic except certain "named" websites. Could I block all traffic to the internet in FW rules but then still allow access by group in App Control Blade? I haven't been able to get that to work right.
Interested in others thoughts!
