I have a Windows Server 2016 (Datacenter Core) running DHCP server role which is not responding to DHCP requests which come from a DHCP relay but is responding to DHCP requests on the local network.
The server running the DHCP role has an ip address of
The DHCP relay is a pfSense router with two adapters and addresses
172.30.255.254/16 and is configured to relay DHCP requests from the
172.30.x.x subnet to
netsh on the server shows the DHCP requests arriving with the relay agent field correctly populated (
172.30.255.254) but the DHCP event log doesn't show any activity.
The DHCP server is fine handing out leases on the local network.
Manually setting an IP for a host in the
172.30.x.x range works and when that's done it can ping the DHCP server and the DHCP server can ping it so the router is doing its job fine.
Am I doing something obviously dumb?
