We had Paloalto Globalprotect VPN version 5.0.9 on our environment. We recently upgraded our VPN client to Globalprotect version 5.2.4. Right after then I see issue in resolving external dns as shown below.
After connecting to globalprotect VPN, When I try to do nslookup for any external website, resolution happens using internal dns server within our network but not through 8.8.8.8.
Moment I disconnect my globalprotect vpn session, I am able to resolve (do nslookup) for public website using google dns.
Has anyone faced this issue and have a solution?
Works not:
C:\Users>nslookup google.com 8.8.8.8
Server: UnKnown
Address: 8.8.8.8
DNS request timed out.
timeout was 2 seconds.

*** UnKnown can't find google.com: Non-existent domain
Works fine:
C:\Users>nslookup google.com
Server: <internal dns server>
Address: <Internal DNS Server>
Non-authoritative answer:
Name: google.com

can you go into more detail with client version and GP app setting for split tunnel DNS.
