GlobalProtect DNS issues in Windows after disconnect

fhewiufhwefhwe — Tue, 14 Apr 2020 19:02:24 GMT

I am using GlobalProtect 5.09 with PanOS 9.0.7.

While using dual monitors with a split-tunnel VPN, I find that when VPN disconnects dns resolution is still trying to use internal dns servers. I am forced to reboot my desktop at home multiple times per day when using remote desktop with two monitors, or to use rdp on a single monitor.

The dual monitor remote session freezes multiple times per day, often requiring me to signout of windows. After the signout, I no longer have DNS resolution and have to reboot. Same thing happens with VPN disconnects.

Any workarounds? Should I use external DNS as a secondary in the GlobalProtect gateway settings? I also had the same problem with the prior version of GlobalProtect client and PanOS.

Hi,

I don't quite follow your question. Can you please elaborate?

GlobalProcect agent disconnects.

Nslookup still points at internal network DNS resolvers specified by the gateway, not the OS dns resolvers such as 8.8.8.8 for google dns.

Found a solution. When I added satellite tunnel and allowing authentication from local auth or certificate, the issue went away.
