Global Protect DNS/Split tunneling issues after Laptop goes to sleep

HoomanF — Tue, 15 Feb 2022 02:30:52 GMT

Hi all,

We have GP 5.2.9 and since the upgrade some users having split tunneling issues when laptop comes out of sleep. Every time laptop gets out of sleep some users get issues with connecting to SharePoint and internal apps. Internet works fine.

When user do "Refresh Connection" on Global Connect, it sometimes resolves things, but the most effective resolution is to restart or resetting the wireless NIC. We've raised it with TAC but no luck.

Anyone else have seen this issue or know any fix?

Thanks

I have been messing around with split tunneling the last couple weeks and seem the same sort of issues with Teams/Sharepoint/Outlook. In particular, switching between gateways borks MS apps and sometimes trying to send a message in Teams while disconnected (always on VPN) permanently hangs teams in "offline" mode. It seems to be something in the security tokens Teams/Sharepoint/etc is sending back and forth and whether it goes over the VPN or direct on any particular connection (because the apps talk to all different IPs spread all over the place). I have found that putting every known MS block in the split tunnel solves the problem... but that raises other security issues.

Have you set your split tunnel by the 'Optimize' group IPs in the MS split tunneling doc, or a custom list?
