Hello all,

Sometimes I get this in my logfile :

kernel: IP_MASQ:reverse ICMP: failed checksum from 195.64.6.130!
Dec 28 00:10:33 zwiffelzwaffel kernel: IP_MASQ:reverse ICMP: failed checksum
from 213.7.32.37!
Dec 28 12:17:51 zwiffelzwaffel kernel: eth1: Setting Rx mode to 1 addresses.

I am not sure how to interpret this, because , as yet, I don't know enough
about ICMP.
What is happening here, is it serious ? The kernel puts it also in
/var/log/warn, so...

anyway, thanks in advance for any response....

JohnvD
