Post Firewall still responding to ping


I am a complete Linux newbie who has just installed Red Hat Fedora Core 1. For the most part I have my system fully functional, but I have one question.
I setup the firewall included with Fedora and have passed all of the online security tests except for one issue. My computer is still responding to ping requests. How can I get my computer to stop replying to pings?
Also, can anyone recommend a good free firewall that maybe they feel is better than the one included with Fedora?

Thanks for any help.

Hi,

Try:
# echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all

iptables -A INPUT -p icmp -j REJECT --reject-with icmp-host-unreachable

This will reject ICMP packets to the pc.
