Hi there! I'm wondering what's the purpose of the field "domain name" on each DHCP interface service. No matter what I put there, the DHCP will always assign the system domain to all devices and ignores the domain on each interface. Should this work like this?
That is a feature/bug of the client, not on OPNsense. Full details of the spec: https://www.rfc-editor.org/rfc/rfc2132
