I had a similar issue. It was because of packet reassembly on pf running on
FreeBSD. If you get the login window but it drops after that most likely its
because of a similar issue.

Hi Teddy,

I don't know the ins and outs of how PPTP VPNs work. Don't think I
want to - MS VPNs are known to be somewhat insecure. However, the
packet forwarding works for "ping" packets, so I don't see why it
wouldn't for RDP packets, at least as far as IP addresses go. Getting
the right port is another matter, maybe, but surely any VPN would
handle that, wouldn't it?

As for why I use PPTP, it's because the company provides that and only
that. If I want to VPN in, that's what I have to use.

Changing firewall permissions ain't going to happen. I don't have
control or sufficient influence. So to run my desktop remotely I have
to tunnel through PPTP.

Thanks, Colin
