Broadcast packet limit is disabled on everything.
I'll open a new cambium ticket. Last time i opened a ticket the
problem cleared up for about 3 months so I couldn't get them any data.
So maybe it just needs to be threatened again.

Talk to Cambium. Sounds like the broadcast packing isn't making its
way back. Do you have any of the multicast/broadcast things set?

I've had this problem at limited times for a couple years, and I've

problem.
Mikrotik Router providing DHCP -> UBNT Edgepoint S16 -> EPMP 5ghz AP
(1000 or 3000) -> EPMP SM F300 -> EPMP 1000 2.4 AP (nonGPS) ->
EPMP 1000
2.4 SM -> Customer Router.
The Customer router will lose it's DHCP lease, and be unable to
renew.
Mikrotik log fills with 'Offering lease without success' Rebooting
the
EPMP 1000 2.4 AP (nonGPS) is the only way I've found to fix it.
It does
not seem to affect any customers who's router is directly connected
directly to a F300 radio. Only one's that are using the EPMP1000 2.4
radio to extend the network.
This has happened on at least 5 sites now, and it's becoming very
annoying. Previously when I've posted, some people mentioned some
Allow
firewall rules for DHCP Traffic in the mikrotik, those don't seem
to help.
My new piece of information yesterday is that I'm migrating customers
between 2 grain legs about 200 yards apart (no truck rolls, just
changing preferred AP). Both grain legs are built with EPMP 3000
Aps.
I have a customer that was installed on the new grain leg, has a
EPMP1000 2.4 AP (nonGPS) that feeds 4 EPMP1000 2.4 SMs on different
buildings and has been working fine for months. They have now had
this
DHCP Issue twice now in the last 24 hours None of the 4 buildings
could
get a DHCP Lease. Rebooting the 2.4 AP immediately fixed the
problem.
So It's almost like this is triggered by another 5ghz SM on the
3000AP.
All SM's are set to block a DHCP Server below the SM.
It's just strange that rebooting the 2.4 AP always fixes the problem.
Until it starts happening again, from a few hours, to several
days. If
I put the EPMP1000 2.4 SM into NAT mode, it seems to be able to get a
DHCP lease from the mikrotik just fine.
Open to any ideas.
