I believe this is a function of the DNS server the client is using.

What DNS server is being sent to the client?

Also which flavor/version of he VPN client do you have installed?

Hi Dameon

It works as followed by this link.

windows - Reverse DNS records not registered when using DHCP - Server Fault 

But not sure why no this issue for Cisco Anyconnect and Palo Alto Global Protect.

I'm guessing we don't set that parameter by default and they do.

I assume you're setting this on the VPN interface, right?

Yes, but no this setting on VPN interface for Anyconnect and Global protect too.
