DHCP request is being relayed from a server in a different subnet to the ISC-DHCP box. ISC-DHCP is not responding

dhcpd.conf is like this:

subnet 10.0.1.10 netmask 255.255.255.254 {} 

host test {
  hardware ethernet 32:b8:ee:57:1e:e0;
  fixed-address 192.168.200.222;
  option routers 192.168.200.1;
  option subnet-mask 255.255.255.0;
}

DHCP request is arriving at this server from 10.0.1.11 but no response. I see this in the logs:

DHCPDISCOVER from 32:b8:ee:57:1e:e0 via 10.0.1.11: network 10.0.1.10/31: no free leases

Any thoughts? There is nothing in the leases file for any of these subnets

  • So we're understanding, you're expecting host with MAC address `32:b8:ee:57:1e:e0` to be assigned the only available IP address in that subnet, 10.01.11, even though something is already using that address and your DHCP server is communicating with it? – Greg Askew Feb 09 '22 at 21:14
  • no, host with mac `32:b8:ee:57:1e:e0` should be assigned 192.168.200.222. 10.0.1.10/31 just needs to exist in the config file as that is the subnet DHCP is being relayed from – Dave0 Feb 09 '22 at 22:49
