Table of Contents
Beginning with Shorewall 4.5.4, Shorewall allows matching packet SOURCE and/or DEST IP addresses by their corresponding country. That is done by specifying a comma-separated list of up to 15 ISO-3661 2-character Country Codes enclosed in square brackets ('[...]') and prefixed by a caret ('^'). When a single country code is given, the square brackets can be omitted.
Example - Drop email from the Anonymous Proxy and Satellite Provider networks.
/etc/shorewall/rules:
#ACTION SOURCE DEST PROTO DPORT
?SECTION NEW
DROP:info net:^[A1,A2] dmz tcp 25
Using this feature requires the GeoIP Match capability in your iptables and kernel. That capability requires creating a country-code database.
The Shorewall compiler uses the geoip country-code database to
determine the valid set of two-character alphanumeric country codes. The
location of that database is currently hard-coded in xtables-addons as
/usr/share/xt_geoip/. Within that directory are two
sub-directories:
LE -- contains the little-endian database
BE -- contains the big-endian database
To accomodate both big-endian and little-endian machines as well as
any future ability to install the database at another location, Shorewall
supports a GEOIPDIR option in shorewall.conf(5) and shorewall6.conf(5). The default
value of that option is
/usr/share/xt_geoip/LE.
Recent versions of the country-code database are installed in
/usr/share/xt_geoip/, regardless of endian convention. This
requires modifying the setting of GEOIPDIR in shorewall.conf (5) and shorewall6.conf(5).
The country codes at the time of this writing are shown in the following two sections.
