I try to configure a shorewall in my slackware but whenI give #shorewall start this stop and answer is
Running debug_restore_input...
iptables v1.4.2: Bad IP address `192.168.0.0/24'

Try `iptables -h' or 'iptables --help' for more information.
ERROR: Command "/usr/sbin/iptables -A eth0_masq -s 192.168.0.1/24 -j SNAT --to-source 192.168.0.0/24" Failed

You should post the config for this.

Best guess is that your ip address is defined as 192.168.0.1/24 when you should write it as 192.168.0.1
