Subject: --policy DROP kills everything?

Message-ID: <42A75EF8.7050002@edoceo.com> (raw)
I have this these rules on a host, to protect only this host.

These are the loaded modules: iptable_filter, ip_tables
I cannot make an SSH or HTTP connection to the box.
I was under the impression that a policy of DROP will drop the packets if they dont match a rule.
If I switch the policy to ACCEPT then no problem. If I add a last rule as DROP then it also fails.
If I put a LOG or ULOG before the DROP rule then I can see packes destined for port 80 making it to log, shouldn't
ACCEPT have passed them through? What stupid little thing did I miss?
