try to do some tcpdump at your freebsd gateway pppoe server if there is a
radius packet coming in...

i successfully setup pppoed + ppp as pppoe gateway and authenticating at
radiator radius server on the other machine... the interface card facing the
pppoe clients doesnt have an ip address... let the ppp session take care of
it...
