Comodo Firewall is by far my favorite firewall (out of the ones I know about) because of the largest set of features when defining security rules. There is one part where I think there is need for improvement. I hope this information helps the comodo team make the product more secure.
In “My Network Zones” part of of comodo firewall settings, user can define a set of computers to apply certain rules to. The problem is that for every new item (“new address”) added to a network zone, we can only define a computer by one of the criteria (radio buttons rather than check boxes).
Allowing a user to specify a computer by more than just “MAC” or “IP” or “Host Name” will allow more detailed filtering of incoming connections and will greatly improve security.
If anyone know a solution to this, please let me know, otherwise, comodo should really consider including this capability.
