How to Whitelist a URL in Server 2019 Firewall

windows firewall allows/blocks applications, services and ports
you can't block a specific URL unless you create a rule to block ports 80/443 to the IP address
if they use a pool of addresses you could restrict access to the entire subnet
if the website is only 100.10.11.12 then you could block that traffic to that address /32
or if they have a load balancer and servers could be .12, .13, .22 etc. then you could block traffic to 100.10.11.0/24
that's a close as you will get

That's what I am coming to understand.
Not sure how to "whitelist" a specific licensing server. The is the standard Comcast Business Gateway with no additional firewall.

for traffic going out, shouldn't need to add that unless you manually have restrictions for outbound traffic
do you have any?  is it not working now?

Outbound is unrestricted.
The whitelisting request is from an application. Their support desk says whitelist their license server. To me that would be outbound so I’m not sure what’s up.
I need to narrow down the context of the request.

they're  not talking firewall, they are talking web browser/email application

firewalls don't work on url's they work on ip addresses

^^^^ Layer 3/4 stateful firewalls that is :)
