Hello, i would like to ask/inform about an issues i noticed in past years that occur behind Mt devices. Not sure if problem is on MikroTik or router manufacturer side tho 
So we use two types of conentions of radio CPE in our ntwrk… A and B.
A is for houses where antenna/router is for 1 CPE and Mikrotik does NAT.
B is for flats where antenna is in PTP mode and doesn’t NAT we using dynamic WDS on AP side and station-wds on station side.
Multiple users DHCP through company 2xDHCP severs
For years(10+) it’s working fine. But in past years there were very few cases of issues from B points. It’s kinda rare, but i decided to write it anyway.
So the issue is that if customer has an ASUS router(don’t know if all of them or just certain models) and today another appeared Xiaomi ( to be exact - AIoT Router AC2350) then DHCP session doesn’t work properly.
There are only discover and offer coming through like shown below but ACK/REQ are not. Only those two manufacturers do this so far, every other brand that customers buys works fine to my knowledge.

Done a bit of tweaking and figured out its dynamic WDS fault, once i set station to station-bridge mode, DHCP starts working.
So my question is if anyone else have same issues or any idea what might be the problem, because i don’t think problem is on our side (DHCP server) if it works fine with every brand just ASUS(now Xiaomi as well) causes the issue.
Or is problem on MT side or even our config might be flawed(Im not the author of original AP Dymanic WDS - Station WDS system in our wireless network) ?
