Thank you @PhilipDAth
For Gmail exemptions, all URLs had to be added I understand. if it's for o365, they have bunch of IP and URL. Some other firewalls have application white-listing where in you can exempt o365 alone.
Regarding client VPN restriction, user IP can change based on DHCP. It's not practical to assign Group policy in this case.
From the client list, is there any option to add IP address? Currently, meraki provides only option to add MAC address.
