K..
Possibly, Drop one of the option 82 on the Closest Ap to the server.
Check the firewall settings int he 1K devices to be sure nothing is
being dropped.
Sounds like a broadcast isolation issue or some kind of security measure
turned on by default.. We used to run in to this with the 1k devices and
found allowing
dhcp below sm seemed to correct the issue. I dont remember if it said
dhcp server or just dhcp below sm.

That is the correct layout.
Wouldn't enabling DHCP Below sub just be if there was a DHCP Server on
the 1K system? DHCP Works, it just randomly stops working, and
rebooting the EPMP1k AP brings it back.
I saw this one other time when I tried to enable Option 82 on an FSK
AP. Same things happened, Client router would not get a DHCP Lease.
I never did more troubleshooting of it then, just turned off Option82
in the AP. I'm guessing something strange is happening because 2
devices are trying to write Option82 into the same request?

So to understand what you have is a
3kAP-->300sub--Switch--1KAP--->1kSub correct?
If this is correct then try this..
Ensure that you have allow Dhcp below sub on the 300 to allow those
responses to relay to 3kAP

I'm running into a strange issue that's being difficult to replicate.
EPMP 3k AP W/option82 -> EPMP 300 SM -> Switch
Local Customer and EPMP1000 radio plug into this switch
EPMP1000 2.4 AP (nonGPS w/Option82) -> EPMP1000 2.4SM
I'm using Option 82 so that Sonar can Tie the Public IP Address to
the MAC of equipment on the customer account.
The Local customer off the switch runs just fine, Option 82 records
the EPMP300 SM MAC, it has had no problems.
But the Customer behind the EPMP1000 radio randomly loses the
ability to get a DHCP Lease. The Mikrotik DHCP Server Log just
reports 'Offered DHCP Lease without success'. When it does work,
Option82 shows the MAC of the EPMP1000 SM Like it's supposed to.
DHCP Lease time is set to 3 hours. At some point between 3-24
hours, the customers router will lose its lease and won't be able to
renew it. The only way to get it working again is to reboot the
EPMP1000 AP. Rebooting the EPMP300 SM or the EPMP1000 SM does not
fix it. And it doesn't happen at every lease renewal, yesterday it
ran for 16 hours before suddenly losing it's lease.
I have just disabled option 82 in the EPMP1000 AP and I'm guessing
that will fix the customer, but I lose the ability to automatically
track them in Sonar. I've tried Firmware 4.4.3 and 4.5.5 on the
EPMP1000, it's had the issue on both of them. Anybody run into
something like this before?
