that is exactly what I am seeing, the clients are behind this stupid
little GVC IP0008 machine, and I am using your mpd software for the pptp
server. I know about the "BUG" in libalias.

Is this part of the PPTP spec, that only one TCP control connection can be
open to an IP, or is it a purely libalias thing.

Thanks for the repsonse (and kickass software to boot)
