TLS communication, EAP does not work

not sure what you've done - I've used FreeRADIUS with native radsec
connectivity to proxy EAP to remote servers (RADIATOR and radsecproxy)
and to receive
EAP from the same remote proxies. Would suggest, as Alan had said, to
grab debug and check what the server is doing. its all quite clear
what its
doing (dont be overwhelmed by all the output, just read it step by
step...) - there will be some very ovbious difference between the EAP
and your radtest - likely
to be related to action of server when packet has gone into
inner-tunnel (which, I'm guessing it shouldnt be doing as its supposed
to be proxied
to remote site......)

On the institution level we run RadSec (embedded TCP/TLS in FreeRadius3) to communicate with our FLR, a radsecproxy. So, using this TLS communication, EAP does not work, but turning off it and doing the communication between all servers using only UDP (disabling RadSec at institutions and radsecproxy at FLR), all EAP methods works.
