I'm using OpenWRT 22.03 with dnsmasq and odhcp. I would like to know if it is possible to make custom Offers based on DHCP Options send by client. I cannot use tag based on hostname or MAC because that's unknown. I only know that the client will set some value on DHCP Option 61 and if that value matches some filter, I shall answer with other DHCP options set.
I read about dhcp-script parameter, but there is no much info, and that scripts seems more focused on doing custom actions on the system after DHCP events, not to make custom Offer packets.
