no, but there are some dedicated tools that form TLS tunnels and then 
transport TCP and UDP packets through that tunnel. I've heard of zebedee
for example, it does explicitly state that it does UDP tunneling.  Note, 
however, that this does not automatically do the RADIUS secret handshaking 
for you, you have got to do that yourself.
If you want to give it a try, I'd be interested in hearing from your
