Hi All, The man iptables and ip6tables specifies: "-s, --source [!] address[/mask] Source specification. Address can be either a network name, a hostname (please note that specifying any name to be resolved with a remote query such as DNS is a really bad idea), a network IP address (with /mask), or a plain IP address. .". What is meant by 'network name'? I would like to use some name for the local network that can be used by both iptables and ip6tables.
