Httrack should work with a firewall enabled. I'm not up to date on all of the
other security stuff that is on the more newer versions of Outpost.

Maybe someone that visits this forum uses the newer versions of Outpost and
can help you, or someone on the Outpost forum might use Httrack and can help
you there.

Good Luck, you'll find the answer. But yes, not good to need to disable
Outpost to use Httrack.
