That would be a good idea, but you would have to encrypt most of the
data. The machine would have to have a static IP address and the user
wouldn't be able to modify it... even then, if the user happened to be
on a network which had the same addressing scheme as your private
network, the (probable) traffic that you would not be able to encrypt,
would still pass on. Besides, windows machines are usually "noisy" on
a network so, it would be noticeable and, if someone thought it was
valuable, he/she could try to access on non-secured ports.
My suggestion is the use of 802.1x, and not permitting it to fallback
to "unauthenticated" connectivity.
best regards
