[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [FW-1] FW Log info -- question?
Hi: ICMP is a protocol, however instead of using ports (as per TCP/UDP traffic) it has different types, in which each type corresponds to a different feature of ICMP. A list of the different ICMP types can be found here: http://www.iana.org/assignments/icmp-parameters Whether you should be concerned all depends on the number and type of ICMP requests your firewall sees. Typically ping and traceroute are useful PD tools, but as a whole, the ICMP suite is rather pernicious. Regards.
