Web Proxy - firewall rules

Hello,
I have a problem with the configuration of the web proxy. The same proxy is functioning properly. But I can not create an appropriate rule to the firewall. When you trying to enter a web page displays “Connection timed out”. When you turn off the firewall completely, everything works correctly. So please help in ensuring that appropriate firewall rules.

PS.
This method does not work
