I am investigating Radius accounting proxy with MR as I am about to deploy a heap of access points. My understanding of Radius accounting via proxy means all accounting packets come from a single source i.e. Meraki clouds rather than directly from each access point.
This means opening up port forwarding from Meraki dashboard to the appliance that is handling these requests. This is not a problem however in the Meraki firewall information page the information shown for Radius accounting doesn't make sense to me.
I was expecting a public IP for a Meraki server but instead it shows the local IP of my security appliance.
Is this correct or have I misunderstood how this works?
