Hello,
Could somebody please explain the 'iptables -A INPUT -eth0 -m state --state
NEW -j DROP' a bit more for me ? I understand that it won't allow any
outside initiated inbound connections into a network.
Correct.
However occasionally if
I'm doing a tcpdump we see things like:
21:04:48.935367 IP 82.29.180.221.15378 > 213.17.40.204.4154: R 0:0(0) ack 1
win 0
These are INVALID, not part of any connection.
So if you use
-i eth0 -m state --state NEW,INVALID -j DROP
you should see the expected result..
