I don’t know if Comodo Firewall can do this already, but I was thinking of adding additional security by adding a rule to my current rules that only allows my MAC address to be the only one that works and blocks all other MAC addresses. I don’t want to go through all my rules for all my programs and add my MAC address to them all, as I would be doing that just about all day. Is there a way to make it apply to all of them without having to tweak each one? If not, could you consider making this possible in the new CIS 6?
