a new script based package called "banIP" to block
incoming & outgoing ip adresses/subnets via ipset.
Features:
* a shell script which uses ipset and iptables
to ban a large number of IP addresses
published in various IP blacklists (bogon, firehol etc.)
* support blocking by ASN numbers
* support blocking by iso country codes
* support local white & blacklist (IPv4, IPv6 & CIDR notation)
* auto-add unsuccessful ssh login attempts to local blacklist
* auto-add the uplink subnet to local whitelist
* per source configuration of SRC (incoming) and DST (outgoing)
* supports IPv4 & IPv6
Strong LuCI support:
* easy interface to track & change all aspects of your ipset
configuration on the fly
* integrated IPSet-Lookup
* integrated RIPE-Lookup
* Log-Viewer & online configuration of white- & blacklist
LuCI-Screenshots will follow in the second post.
