Hi people out there,

this is my first post, so wann say hi to you :-).
My name is Michael and I'm happy. Got a lot of knowledge already out of here - so thx for that!

I have a difficulty and don't know how to solve it. I googled an searched the forum but nothing has helped.

I have one proxmox node with one container and two vms. the container is a pihole lxc and the vms is one home assistant machine and one docker host. pihole is my dns server and also act as DHCP server.
when I create a new vm, the vm gets all the information from the DHCP so that internet works and all is fine. my problem starts when I wann assign an fixed p through a configured static lease in pihole.
I grab the mac, add the entry in pihole wit associated ip and hostname. then I reboot the vm and.... and then I have the same ip as before, from DHCP and my static assignment gets ignored.
I already disabled the firewalls on vm, prox and datacenter layer. what could be the problem here? PiHole is already configured to accept requests more than one hop away..
/etc/network/interfaces on the vm with not recognizing my static lease:
iface en

as you can see deb-dock-01 gets always the 199 instead of the static lease 247
