We absolutely want our Internet based clients to use the CMG, we do not want them to behave as On prem clients unless they are indeed on prem. But we have an issue, when the CM client tries to establish its location it thinks it is an Intranet managed device as its global catalog queries are successful.
We tried using ZPA connector IPs as a AD site, but not helping as SCCM is picking the client's local IP. Then thought of adding rfc1918 addresses as a boundary group and assign to CMG, but we have some sites already using it in internal network, so skipped it. Also blocked on-prem MP traffic over ZPA and thought devices will be re-directed to CMG, no luck with that too.
How we can make the client think it is on the Internet and reidirect to CMG??
Any help is appreciated.
