I have always been uncertain how to set firewall rules for ICMP.
Sure could use some help. Which of the following should be:
(1) allowed incoming (2) allowed outgoing (3) allowed both
incoming and outgoing.
ICMP 0 echo reply
ICMP 8 echo request
ICMP 3 destination unreachable
ICMP 10 router solicitation
ICMP 11 time exceeded for datagram
Are there any others that should be added to the list?
Thanks
