Pfsense Squid 3 Proxy Non transparent firewall :Authentication :rule Issue

[Abhishek]

For monitoring and network usage based on IP/username  i am using squid 3 with wpad but i noticed even though i configure squid in non transparent mode i find my mobile is able to use whatsapp etc without loging (using squid authentication )

when i manually open mobile browser its asking for authentication  , so  i think default block port 80 rule is working but whatasapp is able to access internet because its using port other than port 80 , so i guess all software using non port 80 port will be able to access  internet without getting authenticated using Squid Local account

so what is the best way i can setup firewall rule so that user need to open browser enter usernaame and password then only all application should get internet aceess  ?
