Web Filtering

[lphattingh]

Hi, I need to restrict some of my users buy groups. Admin, Sales, Accounting
Admin need full internet access http and https
Sales Only to corporate web for mail.
Accounting limited to SOME http and SOME https selected sites, Skype
This I can do and have working with Firewall, Aliases and Rules
THE PROBLEM IS
Accounting also has to have the TEAMVIEWER app to connect to remote sites, and this I cannot get to work.
So I changed to Proxy with SQUID, Now TeamViewer is working, but I cannot control selected HTTPS sites, or I block all o allow all, and the users just put https://wwwfacebook,com or https://www.youtube,com and stop working,
Any Ide that can help me. To get my blocking and TeamViewer working together?
