The latest Chrome version (66.0.3359.158) is using the Chromium DNS-resolution method, which overrides our addDomainFilterRules API. To fix this, you need to force Chrome to use the system’s DNS-resolution. This is done by using port 53 as an argument for the Firewall prohibited policy to block Chromium DNS resolution.
