Country Settings

• Make sure not to block any countries where your server may be pulling yum or apt-get updates from otherwise yum or apt-get will fail when you try to grab any package updates.
• Country and ASN blocks apply to incoming connections only.

Deny countries to all ports - CC_DENY
Deny whole country or ASN CIDR ranges. The CIDR blocks are generated from the Maxmind GeoLite Country database http://dev.maxmind.com/geoip/legacy/geolite/ and entirely relies on that service being available.
Default: empty

Allow countries though all ports - CC_ALLOW
Allow whole country or ASN CIDR ranges. Warning: this option allows access through all ports in the firewall.
Default: empty

Only allow countries and filter - CC_ALLOW_FILTER
Only allow access from the following countries or ASN but still filter based on the port and packets rules. All other connections are dropped.
Default: empty

LFD blocking ignore countries - CC_IGNORE
Prevent the login failure daemon from blocking IP address hits for the following countries or ASNs. CC_LOOKUPS must me enabled to use this option.
Default: empty

Ignore CIDR blocks smaller than - CC_DROP_CIDR
Ignore CIDR blocks smaller than this value when implementing CC_DENY / CC_ALLOW / CC_ALLOW_FILTER. This can help reduce the number of CC entries and may improve iptables throughput. This will deny/allow fewer IP addresses depending on how small you configure the option. Set to None to block all CC IP addresses.
Default: empty

Ipv4 address lookups - CC_LOOKUPS
Display Country Code and Country for reported IP addresses. This option can be configured to use the MaxMind GeoLite Country database or the more detailed MaxMind GeoLite City database at http://dev.maxmind.com/geoip/legacy/geolite/
Default: 1 Range: 0-3

IPv6 address lookups - CC6_LOOKUPS
Display Country Code and Country for reported IPv6 addresses using the MaxMind Country IPv6 Database. This option must also be enabled to allow IPv6 support to CC_*, MESSENGER and PORTFLOOD.
Default: 0

Maxmind DB retrieval interval - CC_INTERVAL
How often the login failure daemon will retrieve the Maxmind GeoLite Country database for CC_ALLOW, CC_ALLOW_FILTER, CC_DENY, CC_IGNORE and CC_LOOKUPS (in days).
Default: 7 Range: 1-31
