Sorry, I don't think that's possible. If the WiMAX client is only 
capable of EAP-TLS, you must do EAP-TLS. And EAP-TLS requires a complete 
TLS negotiation and completion.

I assume it's impossible for you to enable EAP-TLS for some reason?

If you do that, the WiMAX client will basically see this:

client: EAP-TLS: TLS client hello
server: EAP-Success <no data>

...and the client will assume something has gone wrong, because it was 
expecting a TLS packet back. This is what I mean when I say you can't 
interfere with the outer tunnel - it's *designed* that way to be secure 
and prevent interference.

HOWEVER - possibly the WiMAX client is dumb, and will do this:

client: EAP-TLS: TLS client hello
server: EAP-Success <no data>
client: Ok, that's fine

If so it's insecure, but it will solve your problem.

Try this in sites-enabled/default:

authorize {
   # Put any comparison you like here
   if (Calling-Station-Id == "the_wimax_mac?") {
     update control {
       Auth-Type := Accept
     }
   }
}

...but I doubt it will work.
