This is my dilemma.

My Linux box (Joey), cannot be pinged by other computers on the network.
But it (Joey) can ping other computers.

Used shorewall as a firewall but didnt really know how to configure it.
Can someone help pls!?

I havnt used Shorewall before but try this

echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all
