Ooook, so it really helps when:
1. You figure out that you're running a third-party firewall, even when
that third-party firewall is actually a first-party firewall. (Windows Live
One Care)
2. You actually _read_ the instructions that come with the tools.
I have determined, without a doubt, that GRE is NOT getting through to the
laptop from which I'm trying to make the connection. 1723 is fine.
So, why would that be?
Now remember, I have another machine in this building going through the
same router and it has no trouble receiving GRE. It's XP Pro SP1.
It's definitely within the computer. It's not the router.
