Probably not relevant, but is the Mikrotik port part of a bridge, and if so, is RSTP enabled? I only mention that because I get weird problems if I enable RSTP on Mikrotik bridges, in fact I turn STP off entirely unless the topology is such that a bridge loop could occur.

Basically, we assign an IP to a MAC in Sonar. That is written to the DHCP server in Mikrotik (basically create a DHCP reservation). Client radio connects and the DHCP request is forwarded to the Tik with the DHCP server running. The Tik assigns the IP and away we go. Sonar doesn't know about successful DHCP assignment or not, we always check the DHCP server to see if it is Waiting, Offered, or Bound. But ours might be quite a bit different without Option 82.

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. >> >> David Coudron >> >> >> -----Original Message----- >> From: AF <af-boun...@af.afmug.com> On Behalf Of Nate Burke >> Sent: Sunday, September 20, 2020 11:40 AM >> To: Animal Farm <af@af.afmug.com> >> 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.
