Re: Is it possible to use CHAP authentication with pam_radius?

You could try to use radsec, i.e. RADIUS over TCP https://wiki.freeradius.org/glossary/RadSec No idea about the current state of support in FR, but there is a tiny software called radsecproxy. Install it on either side of your connection and let it handle the outside traffic over TCP/TLS. This is e.g. in wide use between eduroam members.
