I got my wireless broadband card going, and enabled connection sharing,
now that that works, I'm soon going to tackle the VPN and see how far I
get before I call Craig. :) To that end, I noticed that when I enabled
connection sharing, it gave me a list of 5-10 different protocols and
their associated ports, asking me if I want them to be shared. I said
yes to them all, but I'd like to get back in and also have the VPN ports
opened as well.

I supposed I could just look in FiltCfg and see which the ports are
because we probably have an existing filter in there already.
