Hi! Im tired because I have tryed to run iptables on my system too times. The problem is that I dont have the dynamic library /lib/iptables/libipt_MASQ.so, but anybody have it! I use Gentoo Linux on kernel 2.4.20. I have compiled all netfilter options as modules althoun I tried also installing it into the kernel system. I only want, by now, this rules for the iptables tool: iptables -P INPUT ACCEPT iptables -F INPUT iptables -P OUTPUT ACCEPT iptables -F OUTPUT iptables -P FORWARD DROP iptables -F FORWARD iptables -A FORWARD --match mac --mac-source 00:c0:49:c9:d3:f1 -j MASQ iptables -A FORWARD --match mac --mac-source 00:c0:49:bc:9f:08 -j MASQ iptables -A FORWARD --match mac --mac-source 00:02:8a:3a:77:b7 -j MASQ iptables -A FORWARD --match mac --mac-source 00:90:d1:08:19:8d -j MASQ But the problem is when iptables execute '-j MASQ', telling me that libipt_MASQ.so doesn't exist. What should I do? I can't find an explication. Sorry, but I am from Spain and my English could be poor for you.
