I unfortunately had to move on from using Comodo after so many good years because the ‘COMODO Internet Security Firewall Driver’ doesn’t function with a TUN adapter, which are the most commonly used virtual adapters with VPN clients. And as previously mentioned, this incompatibility makes the Firewall completely useless and basically obsolete for many VPN users.
The following thread started Jun 2022 is about this and my post from earlier this year has a video demonstration to play showing how the incompatibility with a TUN adapter makes the Firewall completely defenseless.
