Sophos ZTNA nslookup probelm

Hello,
as soon as I activate ZTNA on the respective end devices, nslookup no longer works and it always tries to resolve via the IP 100.64.0.3. This would be the DNS server of the Sophos ZTNA TAP adapter.

Which setting must be made here so that the name resolution works again?

Thank you!

This is an pretty old issue of nslookup.

nslookup simply use one DNS server and "gives up".

It should not influence your client in any way, as all tools try multiple DNS servers.

Other vendors have the same challenge:

You can use nslookup like this: nslookup google.com 8.8.8.8
