I have configured FreeRADIUS to as a DHCP server which offers IP addresses based on the option 82 values added by a DHCP relay. In cases where the client sends a unicast renew request bypassing the relay, the option 82 values are queried from an instance of rlm_cache which have configured to keep a record of leases. (This replicates the option 82 "Stash" functionality in ISC DHCP Server). A bit of unlang is involved to check that the lease is valid and take care of clearing out the cache, but it is all fairly simple.
I've pushed changes to the v3.0.x branch which should help. They allow the server to encode and decode lease query packets. You will need to: - add a "dhcp DHCP-Lease-Query {...}" section to raddb/sites-available/dhcp - have the section return "ok" - have the section do: update reply { DHCP-Message-Type := DHCP-Lease-Assigned # or whatever you want to return DHCP-Hardware-Address-Length := 0 } I think that should now work.
