I've just installed it and it reads stealth at grc.com. I know it's a one way firewall, but how does it stack up in protection compared to ZA, Sygate, and some of the others, or is it even possible to compare firewalls that way? I know people say Windows firewall isn't all that great. Is ghostwall a lightweight firewall along Windows lines, or is it more heavy duty? Do any of these questions even make any sense?
