19.7 Legacy Series / Re: Using Opnsense as DHCP server

It looks like what you are doing is trying to use dhcp helper/relay type configuration. ISC dhcpd does support it but this feature is not currently implemented in either *sense project. They may not have enough people demanding it to make it worth the time it would take to implement/it is probably lower on the priority list unless someone wants to step up and implement it in a good way. There are several issues on github for this already including https://github.com/opnsense/plugins/issues/1105
In general I would say if your network is large enough to need the complexity of the dhcp relay you would probably be better served by building your own dedicated hosts for it anyway in which case it shouldn't be an issue. To set things up the way it is currently you would just need to create vlan interfaces on the OPNsense firewall, you will need ip addresses and access to the networks you want to have connect to the internet or other networks anyway right? In my mind its not a big deal for most smaller networks to just set it up the straight forward way...
In case you just missed it look under interfaces, other types, vlan, and you can click the add button. All you need then is the parent interface it will be on and the vlan tag.
