Block all Website Except for Google and Yahoo



  • Hello there guys.. im tryin to create a rule to my pfsense to block all websites except for google and yahoo.. very much appreciated your help.



  • Don't do it via firewall rule, do it via squid & squidguard.  Firewall rules only understand IP addresses, and coming up with a definitive list of all IPs used by Google and Yahoo (without breaking other stuff) is very difficult.  Squid and squidguard work on URLs.
