DHCP Fails

Hi all,

I have install Pi-Hole with this Tuto. Perfect !
All the Mentor DNS work, but i have big problem.
After 1h of use (pi-hole) i'm disconnected from internet to all DHCP computeur (static work fine !). And at this time, DHCP down (dhcp work on my synology, not on pi-hole), and when i restart DNS, he "shutdown" the pi-hole service, i access to the admin interface, but no query on DNS.
If i restart dnsmasq service, i have error (already in use), i kill all 53 listen's service, i restart dnsmasq, it's work fine ! .... For 1h (time of dhcp lease on synology), and internet shutdown again..

Have you an idea ? I have down my DHCP's synology, activate at pi-hole, but no query to dhcp work :frowning: (it the same ip to synology..), and meanwhile, the static's IP of my computer work, and DNS at pi-hole too...

If U R dev, my token : 1vnl4mfdsr

Thx.

Sorry for the english, i'm a bad french user ! :wink:

Are the DHCP ports forwarded from Pi-hole's docker?

It's not a docker file, juste a .deb file :slight_smile:

So your issue is that the DHCP server on synology is not working? What exactly is failing and when?
