I had comodo firewall before after I reformated my hard drive and reinstalled the OS, I installed Comodo firewall pro. after I installed it, my internet stopped working and I found out that my ip adress had been changed? does anyone know the proble with that.
It’s possible (this is the case with my ISP) you’re assigned a new ip when rebooting. If you haven’t tried it yet, a quick fix might be running the Stealth Ports Wizard (selecting ‘stealth my ports to everyone’) this will allow your outgoing connections while blocking all but the critical incoming attempts. You’ll find it in Firewall.
Good luck mon frere.
