I just downloaded Comodo Firewall Pro, and it's default network control rules go: 0. allow all tcp/udp out 1. allow all icmp out for echo requests 2. allow all icmp in when fragmentation is needed 3. allow all icmp in when time is exceeded 4. allow all IP out for GRE protocols and 5. block & log IP in/out for all protocols. Now because of the block & log IP rule, my ISP (Comcast) is unable to send and receive info. The internet still works, but when I look at the traffic it says "access denied" to all attempts, in or out, dealing with comcast. Is this a problem? Will my internet stop working? Will comcast shut off my service?
