At the request of a customer, I need to use of the filtering of URL. We need to permit 250 addresses with a protocol HTTPS and to block all the others URL! But on the router PfSense it is not possible to authorize a pool of URL and block all the others. I looked in "package" them with corn not way to find what I want!
The idea is to make this blocking on one VLAN predefined.
Have you solutions? In my network I have Aruba 225/103/205, a router PfSense and switchs Cisco 2560/2650.
you could create an alias & use that alias in firewall rules. (it'll be ip based, not url based)
