Hmm, I just had it happen again with Option82 in the EPMP1000 AP turned
off. Maybe there's something else going on. Still, rebooting the
EPMP1000 AP is the only thing that fixed it.

I just saw a post in the Sonar forum that looks pretty similar to this one.
We don't use Option 82, but otherwise have Sonar write the DHCP table to the
Mikrotiks. If someone requests a DHCP that isn't in Sonar, we just assign
them a Penalty Box IP address that doesn't have access to the Internet. This
seems to work pretty well.

Subject: [AFMUG] EPMP and Nested DHCP Option82
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?
