I am not running ipv6 and some it is disabled for dhcp. My /etc/sysconfig/network looks a little funny. Also if I am not running ipv6 is there a reason that ip6tables shouldn't just be turned off? Seems like things should be smart enough to say no ipv6, no ip6tables and turn it off. # cat /etc/sysconfig/network NETWORKING=yes yesHOSTNAME=localhost.localdomain
