We are planning for local internet breakout in the branch network with all the internet traffic going to Zscaler via GRE/IPSec tunnel.
The users PC will be configured PAC file.

- Should it be resolved via local DNS server or via Public DNS server IP ?
To forward the traffic to Zscaler via GRE/IPSec tunnel is it required to advertise public IP address into our branch network.
