[Dnsmasq-discuss] DHCP renewal fails if a DHCP relay is used

[Zak Kemble]

Hi, I'm running dnsmasq/Pi-Hole in a docker container with bridged
networking and dhcp-helper to forward broadcasts to the Pi-Hole container.
This is working, but DHCP renewals that send unicast packets to the DHCP
server (specified by the server-identifier option) will fail because
dnsmasq is using the containers internal IP for this option. Would it be
possible to allow overriding of server-identifier so that it can be set to
the docker host/relay IP? I think a similar thing has been mentioned here
https://dnsmasq-discuss.thekelleys.org.narkive.com/M9Rwt2oy/cannot-override-dhcp-server-identifier-option-54
but that was 10 years ago lol

Here's my original issue where I was directed to email you guys

Thanks,
Zak
