this only helps if the router is playing DHCP server as well.
@joaquinain
what is this IP 192.168.1.25 about? is this your internet router? Which Upstream DNS server you configured in PiHole? Can you check pihole -t. It should display Pihole log and you can watch what PiHole is doing on your DNS request. Probably logging would need to be activated >> pihole logging on

well I need to use PiHole as DHCP Server because my Router (ISP device) did not support changing local DNS Server.
