I would look at setting up a two-arm load balancer so that the originating IP address of the client is presented to the radius server. Outside of that, it won’t modify or change any attribute of the packet itself.

How do you mean? What specific things did you have to do for that to happen? (What I’ve seen is the NATed IP come through as the Packet-Src-IP-Address, rather than the machine from whence I was testing.)
