Yep... Bought it for the wifi. Considering swapping the switch for a edgeswitch...

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 :)

Well, I've got plenty of experience of UniFi gear working and then some aspect just randomly breaking lol

Please see my update above :) L2 connectivity is verified for IPv6 and IPv4 - but dhcp is not working.

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:

Code Select Expand


sudo ip addr add 10.0.1.190/24 dev enp2s0
[~]$ ping 10.0.1.1
PING 10.0.1.1 (10.0.1.1) 56(84) bytes of data.
64 bytes from 10.0.1.1: icmp_seq=1 ttl=64 time=0.157 ms
64 bytes from 10.0.1.1: icmp_seq=2 ttl=64 time=0.133 ms

2 packets transmitted, 2 received, 0% packet loss, time 1007ms
rtt min/avg/max/mdev = 0.133/0.145/0.157/0.012 ms


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:

• 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

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.
