Default Re: TS over the internet - directly attach, or require a VPN?

I'm totally new to this and so am liable to get confused about the
issues, but the OP did state that they were *considering* dropping the
VPN part of their setup, which includes a firewall. So they haven't
opened up anything (because they haven't changed their current
firewall/vpn config) and even if they did, they'd still have the
firewall in place.

As I said I'm a newbie to the topic at hand, so I'm even not sure that
what you said doesn't match the OP's question. I've read many posts by
you (Jeff) where the primary message seems to be "don't ever expose your
TS/LAN directly on the internet". I often can't tell exactly what you
mean by that; and this response of yours makes it even more confusing.
What exactly do you consider a safe TS config for use on the internet? I
really want to know. They only direct exposure I have is via TS behind a
cisco firewall that is also a vpn endpoint, with all clinet IP addresses
known. I am hoping that there is a safe way to deploy TS on the internet
that is less rigorous than that, but maybe there isn't.
