I have this these rules on a host, to protect only this host. # Generated by iptables-save v1.2.11 on Tue Jun 7 23:03:58 2005 *filter :INPUT DROP [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -s 127.0.0.0/255.0.0.0 -i lo -j ACCEPT -A INPUT -d 192.168.42.2 -i eth0 -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -d 192.168.42.2 -i eth0 -p tcp -m tcp --dport 80 -j ACCEPT COMMIT # Completed on Tue Jun 7 23:03:58 2005 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?
