Even with Pulse 9.1.10, we're still seeing cases of DNS settings not releasing when the VPN disconnects.
We have split tunnelling enabled but no FQDN specified.
The VPN tunnelling connection profile is manual DNS, search device first
Is there anything we can try other than hoping the next release of the Pulse Client will resolve this?
We have an ongoing investigation for the same issue. i.e., DNS not getting restored.
I could recommend you open a support ticket. We have a test build for checking the same.
The support will share with you the latest details for the same.
