Packets passing trough...

[Jet]

Hi strenuus,

It is possible. what if the packets are:
Packet=1     interface=eth0                src=194.106.188.1
dst=192.168.0.1
Packet=2    interface=eth0                src=194.106.188.1
dst=192.168.1.1

Packet 1 go into rule 6 and packet 2 go into rule 7.

By the way, have you done this?

for interface in /proc/sys/net/ipv4/conf/*/rp_filter; do
  echo 1 > ${interface}
done

Maybe you want to try this first first and reset the counter. And see if it
still happening.

Good luck.
