Does ZTNA tunnels for SAMBA needs private network to be configured so that it could work with WARP questions

Hi, in order to use ZTNA tunnels for SAMBA, other than public host name, do I need to also configured the private network for my tunnel so that the the SAMBA server could be accessible from the WARP client?

If yes, does it has to be my LAN IP address range or any other private IP addresses range is fine.
