Hi,

I'd like to allow only the essential ICMP message messages. This is for a very busy web server using about 60MB/per sec.

I have this list of what I think are the essential ICMP types I should allow. Do you think this is correct?
Am I missing anything ?

ICMP,Type,Code Used By

0     0     Ping
3     4     Path-MTU Discovery
4     0     Source Quench
8     0     Ping

11 0 traceroute

Many thanks.
Regards Rudi
