You can do this via the Sinefa Traffic Shaping Rules. You can find out more details on traffic shaping via this guide – How to Setup Traffic Shaping
The Traffic shaping policies is applied in the following order:
- Ignore - Traffic Shaping rules do not get applied to this application/definition
- Block - Once applied, End users will be unable to use what's defined (i.e. Facebook, Youtube, etc.)
- Shape - Most specific subnet address (e.g. 192.168.0.124/32)
- Shape - Least specific subnet address (e.g. 192.168.0.0/16)
- Shape - Application (e.g. Facebook)
- Shape - Application Group (e.g. "All Software Updates")
- Catch All (i.e. All Other Traffic)
Take for example, if you wish to block all traffic to YouTube and only allow IP segment 10.10.15.0/24 to be able to view YouTube. You can do via the following steps
- Set a Shaping Rule to block YouTube traffic.
- Set a 2nd Shaping Rule to Ignore YouTube for 10.10.15.0/24

- Now only users from 10.10.15.0/24 is able to access YouTube.
