See www.shorewall.net for documentation. There is a *simple* GUI in Mandriva Control Centre to manage shorewall. Editing the shorewall files by hand gives better control and they are well documented.

To enable it edit /etc/shorewall/rules and add the line ACCEPT net fw icmp 8 to allow ping from the internet or ACCEPT loc fw icmp 8 to allow ping from the local network After editing the file run shorewall restart from a root terminal HTH derek -- www.jennings.homelinux.net http://twiki.mdklinuxfaq.org
