I get a lot of

IP_MASQ:reverse ICMP: failed checksum from xxx.xxx.xxx.xxx

but masquerading is NOT active. I mean:

# ipchains -L
Chain input (policy ACCEPT):
Chain forward (policy ACCEPT):
Chain output (policy ACCEPT):

# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 0

Is it normal? What does it really mean (since can't be masquerading issue)?

# uname -a uname -a
Linux srv01.*******.com 2.2.16-3 #1 Mon Jun 19 19:11:44 EDT 2000 i686 unknown

(ok, I know there's an update)

I've found some related messages in list archives but none explain why
it happens.

TIA (please Cc: me, I'm not subscribed)

.TM.
