FreeRADIUS lets you limit what source IP addresses you accept
RadSec connections from, in addition to certifying them with PKI.
If you want. I've never tried it, but you can probably use a wildcard
client stanza with proto = tls.

I think you may be confusing the "secret" with the PSK. The "secret"
in all RadSec should be set to "radsec" because the "secret" is obsolete
if you are using TLS. You need to be removing the cert-related
directives and looking at the psk_query or psk_identity+psk_hexphrase
directives. The comments in the sample config probably need some work.
When you figure it out, send a patch! :-)

See the above github issue... support will vary depending on how close
to the bleeding edge your server is.
