This ferm defines 3 extra chains in filter table (for both ipv4 and ipv6): protected, limited, unprotected. The first drops incoming new connections, allows dns replies and pings. The seconds allows ssh, and rdp ports. The third just accepts the packet. Signed-off-by: Dimitris Aragiorgis <dimara@grnet.gr>
