I’ve been using firewall rules for some time now to restrict traffic to sites. One rule I use for UK based sites is to challenge non-UK traffic. I have an ‘allow’ rule to whitelist IP addresses for necessary services. However I can’t seem to find IP address ranges for Google Ads and other services.
I’m thinking I could whitelist Google Ads etc. with a referrer rule, but ideally I don’t just want to trial-and-error this on live sites, it would be great to just know what’s going to work before implementing it.
Any help would be greatly appreciated!
