Block traffic without sending RST, ACK && ICMP block problem

Comodo Internet Security - CIS Firewall Help - CIS
#1

Hi,

I have two questions.
The first is, is it possible to configure Comodo Firewall to drop packets that match with a Block Rule instead of sending RST packet back?
The second is, i configured Global Rules to Block every incoming ICMP echo-request and allow every outgoing ICMP packet, but after saving the rules i still can ping my OS. What have i configured bad?

Thanks in advance

For incoming packets that match a block rule, comodo firewall will silently drop the packet at the network layer before the packet is passed to the application layer. Because Windows doesn’t see the packet, it can’t send a TCP RST packet. For outgoing packets generated by applications that match a block rule, the firewall will prevent the packet from leaving the system and will generate a TCP RST packet that is sent to the application. This is behavior is for usability purposes so as to prevent the application from hanging waiting for a response and timing out the connection, instead gracefully closes the connection.

The second is, i configured Global Rules to Block every incoming ICMP echo-request and allow every outgoing ICMP packet, but after saving the rules i still can ping my OS. What have i configured bad?

Thanks in advance


Are you running a ping from a different computer to the one with CIS installer or are you are pinging yourself within Windows? What does your global rules look like? If you can, list all the rules in order or provide a screen shot to see what might be causing the issue.
