Depends upon what your default policy is defined as. If the default policy is DENY then you must specifically include an ACCEPT rule for icmp traffic. Askar you can find many iptables help sites via a google search and I have at least one good book on iptables (sorry, forget the title, email me if you want it and I'll post it back to you). That said, I can't say enough about shorewall. I struggled with iptables trying to get everything just right, but when I switched to shorewall (which uses iptables behind the scenes) managing my iptables rules became so much simpler. -- gentoo-user@gentoo.org mailing list
