I am messing around with iptables, trying to learn how it works so that I can build my self a router/firewall and mabey a VPN. Anyway I tried to use a command on my Desktop CentOS3 machine.
"iptables -A INPUT -s 127.0.0.1 -p icmp -j DROP"
now the command seems to have went through because I didn't get any errors, but when I go to ping 127.0.0.1 I am getting a response and my packet loss is 0%. It should be 100% packet loss.
Can anyone tell me what I am doing wrong. I am not trying to do anything yet, just want to learn by exploring.
Try:
iptables -A INPUT -d 127.0.0.1 -p icmp -j DROP
Since you're pinging 127.0.0.1, that's the destination (-d) address, not the source (-s) address.
