I'd like to have a few vlans on hAP AC³ with 7.1rc4 (wifiwave2 is a requirement in my case), but hit an issue with a non-working dhcp server on vlan. Wireless clients send dhcp requests, but sniffer shows no response from the dhcp server. Ethernet clients continue working just fine.
WAN: ether1
mgmt bridge: ether2 and wifi4 (172.16.0.0/24)
main bridge: ether[345], wifi[123] (192.168.0.0/24, vlan20)
I started with a single vlan 20 on the main bridge and ran dhcp server on this vlan. I checked the firewall rules, they don't drop any internal traffic. Please see my pretty basic configuration below. Thanks.
