does comodo firewall make PC full stealth


ZA Pro (paid) version and maybe free version also make PC to be tootally hidden (stealth mode) as far as internet zone is concerned and not so within LAN.
Is the comodo firewall totally hidden or can ports to seen from the internet?



Yes, it does. Stealth based on default options. The common web definition of “stealth” is equivalent to all ports closed and shown.
