Can Mikrotik send src. MAC to Radius Server?

RouterOS General

Hey all,

I’ve set up a network using Mikrotik and a radius server (freeradius) using DHCP with Mac address authentication. Now, my network is setup as below

Client (00:00:00:00:00:CC)
||
Bridge (00:00:00:00:00:BB)
||
AP (00:00:00:00:00:AP)
||
Mikrotik (00:00:00:00:00:MT)
||
RADIUS

I’ve noticed that the MAC address that is being sent to the radius server is the client’s (00:00:00:00:00:CC) but the ARP MAC table corresponding to the assigned IP address is the bridge’s (00:00:00:00:00:BB). I’ve been playing around with Mikrotik DHCP server static leases, and there is an option to “use source mac”, which would be the mac address of the bridge and not the client, is there anyway I can get Mikrotik to forward the source mac to the radius server to be authenticated instead of the client’s mac address?

Thanks.

This is exactly what would happen if you rout the info to the radius server instead of using bridge. In this setup bridge not bad but if you should expand, bridge very bad for broadcasting traffic. Start with routing. Won’t regret.

Can you be a bit more specific?

Are you suggesting that I use the antennas in Router mode instead of Bridge?

That won’t be possible because of our network set-up. We use different subnets for the type of service a customer requires. Some customers require both services, thus why we use our antennas in bridge mode.

Any suggestions?

What service? Mabe some more info on setup?
