We have a use case in which we have say example.com resolving internally(on-prem) to 10.1.1.1, this will resolve internally while you are connected to the corporate network using the corporate network DNS servers. the global protect clients are also pointed to the internal corporate DNS servers. So all the traffic for DNS comes through the GP tunnel.
As soon as we created an external DNS entry for the same example.com to resolve to 22.214.171.124 publically. Linux endpoint users even while they are connected to GP and are using corporate DNS servers, the name resolution for example.com resolves to the public IP and not the private one the issue seems to be intermittent and is affecting multiple clients, This setup does not affect mac or windows clients who use the same internal DNS server over GP VPN.
Has someone come across this scenario before? Any help is appreciated.
