http://greatdialup.com/index.php It supports XPs builtin DUN. OK got the facts & ugly adware part out of the way. When I check my firewall with my paid dialup ISP, I am totally STEALTH. No closed or open ports. On all GRC port scan tests. And 3 or 4 other firewall testing sites. When I use Great Dial Up (adware) ISP. My same firewall, Sygate Personal Firewall v5.5 build 2710. Shows an open & a closed port (79,80). Just on the common ports test at GRC.com. Didn't run the full first 1056 ports test. I don't consider this Sygates faullt. Can I make my firewall fully stealth with this adware ISP? Or is it impossible? Or do I have to finally switch firewalls? Thanks.
