Added note for 'external' addresses of SSDs
# Make a backup of the original default rules: <source lang='bash'>cp /etc/sysconfig/iptables /etc/sysconfig/iptables.original</source>
# '''Stop libvirtd''' and '''restart iptables''' so that you have only the minimal default rules.
# Use the ifconfig or ip address command to determine the IP ADDRESS of your external facing address (i.e. IP address beginning with '''10.x.x.x''').
# Find a partner to '''ping''' your external facing IP address. Was your partner successful? (it should have worked)
# Change the '''default policy''' on the '''INPUT''' and '''FORWARD''' chains in the filter table to '''DROP'''.
