Description of problem:
/sbin/ifup has code fragments like that:
if iptables -L -n 2>/dev/null | LC_ALL=C grep -q RH-Lokkit-0-50-INPUT
and more of other "RH-Lokkit" specific pieces. The catch is that
the current /etc/sysconfig/iptables defines "RH-Firewall-1-INPUT"
chain and there is no "RH-Lokkit" around anymore. Leftovers from
old times? DNS still happens to work even if there are no port
53 specific holes punched through.
Version-Release number of selected component (if applicable):
It's for old compatiblity; it's not needed for the current firewall.
