Hey scty Library,
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.
Oops! I forgot about that.
The LinWiz iptables wizards cannot help you, a router/firewall/VPN application is too complicated for them.
If you do not care about reinventing the wheel, then proceed with your learning experience.
If you just want a router/firewall/VPN, look at Smoothwall. A mountain of effort and expertise has been put into that dedicated firewall distribution, and I suspect there is NO WAY anything you could do on your own could come close.
But if your purpose is to have a learning experience, then you are on the right track.

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.
