0001769: add a default rule to LOG-drop ips on wrong interface ("spoofing")
we want to see if somebody is spoofing internal ips

we read all ips on our interfaces (green, orange, blue)
afterwards we drop & LOG these packets:


we log-drop:
on red
(eth1 is our RED)
-i eth1 -s -j DROP
-i eth1 -s -j DROP
-i eth1 -s -j DROP

same for:
on green
on orange
on blue
these packets's won't be routed - but we want them to be seen in the logs
as these are possible attacks or at least errors in cabling

gets more complex when having more ips on one single IF
No tags attached.
