I think I've arrived at a solution. With v2.87 and the following configuration, clients are now receiving the expected leases:
# /etc/dnsmasq.d/172.18.0.0-16 dhcp-range=set:172.18.15.0-24,172.18.15.0,static,255.255.255.0 shared-network=enp2s0,172.18.15.0 # /etc/dhcp-hosts/172.18.15.0-24 00:c0:b7:f1:0f:65,rack7-pdu1 00:c0:b7:f1:a3:71,rack7-pdu2 # /etc/dhcp-opts/172.18.15.0-24 tag:172.18.15.0-24,option:router,172.18.15.1 # /etc/static-hosts/172.18.15.0-24 172.18.15.106 rack7-pdu1 172.18.15.107 rack7-pdu2 This leads me to another question: There are 129 other subnets whose gateway IP addresses will be moved away from the dnsmasq server. Is it allowed to have many shared-network directives in the config? shared-network=enp2s0,172.18.0.0 shared-network=enp2s0,172.18.1.0 shared-network=enp2s0,172.18.2.0 < … > shared-network=enp2s0,172.18.125.0 shared-network=enp2s0,172.18.126.0 shared-network=enp2s0,172.18.127.0 shared-network=enp2s0,172.18.128.0 Thanks again for all of the help. -Rich On Thu, Oct 27, 2022 at 10:44 AM Rich Otero <rot...@editshare.com> wrote: > No, I'm not setting dhcp-rapid-commit in my config.
