If you have a modem\router be sure its fully stealthed. A hardware firewall is your fist line of defense. Then simply go to Firewall\Stealth Port Wizard in Comodo 3.0 and select the bottom one for block all incoming connections.
Question...
When I select the above "Block all incoming connections" and then click "Finish" I get the Success box pop-up stating "Your firewall has been configured accordingly". Great! However, if I go back then and re-open the "Stealth ports wizard" I see the top button highlighted and not the "Block all incoming connections" button which I previously selected. Did the protection drop or default back to the top option (if so, why?), or is this just a default choice when openning this wizard and my previous choice is still active ("Block all incoming connections").
Thanks, hope my question is not clear as mud.
