unknown allows you to forward all unknown users to another RADIUS
server (configure a domain named DEFAULT in the RadRoamDomains table).

Echo means echo back the auth request attributes after the reply
attributes. It should NOT be used in any general implementation.

This is a generic step, not proxy specific.

Checking the secret is also a generic step, not proxy specific. The
2.5.2xx version can remove the domain from the username, without
proxy as well (trim name feature, although it does remember the domain
for proxy, if proxy is enabled).

Correct. It does add Proxy-State to the packet as well, though.

You don't have to register the terminal server, just the RADIUS server
the sends the request.

Thats correct.

Sounds like everything is ok. Should only take a couple of seconds to
restart the RadiusNT service on the first server.
