Hello,
I have serveral RB433's out in the field and each one has a dhcp server enabled on a bridge which consists of eth2,eth3 and wlan1. I've tested the dhcp server is working on a switch and connected 3 unifi ap's to this and they received IP addresses from the DHCP server. When we connected the RB433 in the field and then connected the unfi ap's, the log on the RB433 states that it deassigned the ip address on each ap, but never assigns them back again. Any help would be appreciated. Thanks.

This can be closed. It was a physical problem.
