EAP-Peap-MSchapv2 proxy from innertunnel

 I guess I assumed the   id: in the TCP dump   below was the "EAP Response Identifier"  maybe not ? Is there a different
EAP response identifier ?

 I actually have been running with debug radius -X. Obviously a lot longer output than just the TCP dump.
That is why I first tried just the TCP dump. I guess I was also hoping somebody might have just
had a thought about a common configuration issue...

 I just went back to run another test and the proxy server now seems to be down. This server
is run by our network group and I don't know when it might be back..  As soon as it
comes back, I will run and capture the debug and see if I can see the EAP-message AVP's ?
I will also post the debug

EAP Response identifier sent by the client has to match EAP Request identifier
sent by the server which would be ISE.

can you see the EAP-Message AVPs sent and received by freeradius? identifier is the second
