csf invalid chain
Greetings
I use csf (Centos 6) 64bit and noticed some "invalid" when restarting csf.
from csf -l :
Chain INPUT (policy DROP 0 packets, 0 bytes)
num pkts bytes target prot opt in out source destination
...
....
17 3438 296K INVALID tcp -- !lo * 0.0.0.0/0 0.0.0.0/0
...
and also:
Chain OUTPUT (policy DROP 0 packets, 0 bytes)
num pkts bytes target prot opt in out source destination
...
...
20 3890 5630K INVALID tcp -- * !lo 0.0.0.0/0 0.0.0.0/0
.....
more:
Chain INVALID (2 references)
1 25 1000 INVDROP all -- * * 0.0.0.0/0 0.0.0.0/0 state INVALID
when restarting csf (csf -r):
...
Flushing chain `INVALID'
...
Deleting chain `INVALID'
Flushing chain `INVALID'
Deleting chain `INVALID'
INVALID tcp opt -- in !lo out * 0.0.0.0/0 -> 0.0.0.0/0
INVALID tcp opt -- in * out !lo 0.0.0.0/0 -> 0.0.0.0/0
INVALID tcp opt in !lo out * ::/0 -> ::/0
INVALID tcp opt in * out !lo ::/0 -> ::/0
any idea?
TIA.
