You're exactly right. It was Unifi that decided that the new DHCP server probably was a rogue one, and filtered offers from it.
Thanks for pointing me in the right direction

I've made *no* configuration changes on the switch - and it was working at some point with OPNsense - and it was working with same configuration on pfsense.
It should be noted that if I set static IP on a host that is connected to the native VLAN, I can ping opnsense just fine:
In addition, IPv6 RA works; hosts get IPv6 SLAAC assigned. This points to the fact that L2 connectivity is correct and functioning.

I have the following configuration:
PF Rules are set to IPV4+IPV6 any type any source any destination allowed for now:
Firewall rules for IGB0.
DHCPv4 is set to hand out for 10.0.1.10-10.0.1.250:
However, clients are unable to get IP. They don't get a reply on DHCP queries. All other interfaces work just fine.
igb0 is attached to a Unifi switch, with tagged and untagged vlans. The setup was working after installation, and with pfsense previously - but at some point it stopped working. No modification was made to unifi side of network.
Any suggestions or pointers are welcome.
- IGB0 - LAN - 10.0.1.1/24
- IGB0_VLAN2 - 10.0.3.1/24
- IGB0_VLAN3 - 10.0.4.1/24
- IGB0_VLAN4 - 10.0.5.1/24
