i just installed cfp with no Defense+ and leak protection on my computer, As prevousy cfp had caused my registry to bcome corrupt and i could not log.
After installing(No defense+ , No leak protection, simple firewall) i ran the stealth port wizard and then verified it on grc.com, it was reaveled hat port 0 and poert 1 are not stealth but closed.
i consider it worth reporting
