Message-ID: <1139204858.2549.5.camel@localhost> (raw)
Are the ICMP Destination Unreachable-Fragmentation Needed and DF Set
(type 3, code 4) packets sent in response to a TCP packet doing PMTU
discovery considered RELATED or does one need to allow NEW connections
for such packets?
By the way, is there a way to specify code number in the --icmp-type
match? I think one can do -p 1 --icmp-type fragmentation-needed but I
usually use the numbers to avoid lookups, e.g., -p 1 --icmp-type 8.
Thanks - John
