Hi Johann,

Could you post the output of both:
#iptables -L -vn
#iptables -t nat -L -vn

The fact that those packets are being logged means that they could ONLY 
be dropped if the policy says to - the packets are getting to the last 
rule in your chain; doing a -j LOG which returns the flow to the chain; 
and then not going anywhere.


Hope that helps.
