DHCP client on systemd-networkd sends requests as broadcast so if
there is more than one DHCP server on the network
all but one will answer NAK: wrong server-ID. DHCP client stops at
the first NAK and ignores the ACK that will be sent.
THe attached patch included a test refusing any NAK that does not
come from the same IP that the request was sent.
Patches like this one, should be submitted upstream and reviewed there.
Can you please create a PR at

Thank you, I added a PR and it was merged yesterday.
sd-dhcp-client: reject NAKs from servers that we did not send an offer
to (#29290) (https://github.com/systemd/systemd/pull/29290)
This change will only be valid for 255. How can we backport it to 252 up
to 254?.
Thanks,
