We're using a wireless mesh network (tropos) whose gateways proxy arp for their clients. Therefore, the hotspot binds the gateway's mac address with the client's IP address. So far, so good - all the clients behind a given gateway show the same mac address, but that's not a problem.

The problem occurs when a client roams to another gateway. Since the mikrotik hotspot sees a bound IP address with a new mac address (i.e. that of the new gateway), it drops the packet.

Is there anyway around this? Can you tell the hotspot to drop the old binding and create a new one if there's a conflict?

Any help appreciated.

I've encountered the same problem - also using Tropos mesh APs. If anyone has an idea on this I sure would like to hear it.

Did anyone ever come up with a solution to this problem? I'm running into the same issue.

Thanks

The solution we came up with was to introduce a layer 3 hop between the Mikrotik and the mesh network. This means the only mac address to show up on the Mikrotik is that of the directly attached router.
