EAP - Anonymous - Proxying

Hi all,
i'm a FreeRadius (and related auth protocols) newbie, my final goal is to
join EDUROAM (!).
I'm playing starting with a stock Ubuntu 14.04 + FR 2.1.12.
Following http://deployingradius.com/ i succesfully tested EAP as explained
here http://deployingradius.com/scripts/eapol_test/.
Then i applied some changes to configs in order to forward requests for a
specific REALM (generated by eapol_test using ttls-pap), to another FR (2.0
pre cooked using ZeroShell); it didn't work!
Looking at the output of freeradius -X (attached), it seems that the
problem comes from the "User-Name" field that contains the value assigned
by eapol_test to the "anonymous_identity" field rather than that assigned
to the "identity" field; then FR isn't able to select the right destination
REALM because it doesn't known anything about the effective REALM. Things
work if i put the destination FR IP Address in the DEFAULT REALM, but this
configuration is not acceptable for me.
I known that the EAP protocol uses a fake/anonymous identity during phase
1, but until now i'm not able to understand more than this :-(
Any help and suggestion will be appreciated.
