Docker DHCP not receiving requests

Help docker
1

Hi,

I am trying to use this setup and I can see dhcp requests being received in the dhcphelper container but they are not being received at the pihole container.

Any pointers?

Can you share your docker run or docker-compose for both containers?

Have you enabled DHCP in Pi-hole's settings?

Yes, I have enabled DHCP. My reply was to a separate thread and I didn't mean to start a new thread. My response without context won't be very productive.

I moved it to a new thread as it's a new help request. The old thread is linked for context.

Anyways I managed to get it running by using ISC DHCP relay instead of dhcp-helper.

dhcrelay/Dockerfile

FROM debian:buster-slim
RUN apt-get update

RUN apt-get install -y isc-dhcp-relay
