RE: iptables: exe

[Tasha Smith <natasha3641@yahoo.com>]

Ok guys: i think they started up with out any errors:)
"chmod 755 firewall" Then i went to my "rc.local" file
and put "sh /etc/init.d/firewall" at the end and
rebooted and i got no error but COULD NOT see anywhere
saying "firewall starting      OK"  but when i logged
in and tryed the command "iptables vL" I GOT THIS 
----------------------------------------------------
Chain INPUT (policy 0 packets, 0 bytes)
pkts bytes target prt opt in out source destination
0 0  ACCEPT  all   --lo    any      anwhere    anwhere

CHain FOrward (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prt opt in out source destination

Chain OUPUT (policy ACCEPT 14 packetts, 1047bytes)
pkts bytes target prt opt in out source destination
0 0  ACCEPT  all   --lo    any      anwhere    anwhere
------------------------------------------------------
Soo does this mean they started right???
