Hey all...quick question regarding iptables and tcpdump.
Does tcpdump, when run on a system concurrently running iptables (with a very restrictive set of rules), prints the headers of packets before or after the packets are dealt with by iptables? I would assume, if you ran tcpdump on the external interface, that the incoming packet headers would be printed before they get to iptables. Is that a correct assumption?
Danke in advance!
