Unable to turn off PPPoE encryption

I am trying different things on my RB433 to see the effects. I set up a PPPoE profile to encryption = yes, and then changed it to encryption = no.

When I have a local secret the link is not encrypted, when I use a FreeRADIUS server it always is.

My test machine is a Windows XP one, with a RASPPPoE client (although this happened with the Microsoft client as well).

ppp profile:
name=“pppoe-private” local-address=10.55.100.1 use-compression=default
use-vj-compression=default use-encryption=no only-one=default
change-tcp-mss=default dns-server=208.67.222.222,208.67.220.220

The only reply the FreeRADIUS server is giving are:
Framed-Pool := private-pool

This does not happen with my OpenBSD client machine.

Does anyone have any ideas?

This is because the Radius Server sends encryption attributes to the MT. I -highly- doubt that your Radius Server sends only Framed-Pool as you suggested.
