If I read this, this would go around my guards, as they are

<br>
Yeah, they'd certainly be sending whatever information they find
as a
<br>
ruquest to the server on port 443. It looks like normal web
traffic
<br>
because it is normal web traffic.
<br>
<br>
There's also html5 gathering info.

I'm really not having a big concern since I have 2 firewalls
anyway. I
<br>
have a firewall on one device and a firewall on my computer.
So the only
<br>
ports they will see is the one on my first device and not the
computer.
<br>
At least that's my theory.

When you say "close up ports", do you mean make sure there's
no
<br>
executable listening at that port, firewalling that port so
nothing can
<br>
come in or out, or something else?
