Wi-fi clients not seen in FMC

[MarkKruse5137]

When looking at traffic in the FMC I've noticed that I never see wi-fi clients listed. I will see an entry for the AP's IP address, but not the actual client. We have Meraki AP's, ASA with firepower module managed by FMC

Any help would be appreciated.

Hi

 The only explanation I see would be if the client traffic is tunneled  or if you have a different gateway on the network.

Yes, that seems to be correct. Looking at it closer when using an SSID that is configured for NAT using Meraki DHCP, the client can't be seen.

Thanks

There is capwap tunnel between ap and wlc,

Asa allow this tunnel,

Inisde this tunnel the traffic of wifi client is pass.

So asa not see the inner wifi cleint traffic it see outer tunnel ip.

UDP port for tunnel  is 

5247 5248,

Check any traffic with this udp port.
