A problem that comes and goes? DHCP over a “universal repeater/pseudo bridge/transparant bridge/ L2.5 bridge” that fails to make the last step in the process ‘offer->bound’.
With Mikrotik, but also others (https://supportcommunity.adtran.com/t5/Elite-On-Premises-Wi-Fi-Software/BSAP-do-not-pass-through-DHCP-OFFER-to-WiFi-bridge-client/td-p/21378) with exact the same problem.
