README

This plugin will prevent clients with banned IP addresses from logging in.

Both IPv4 and IPv6 are supported. IPv4 is tracked per address; IPv6 is tracked per network prefix (f2b_ipv6_prefix, default /64) so attackers can't evade bans by rotating addresses within their allocation.

Install

Run : composer require inboxcom/f2b.

Database support

Works with MySQL/MariaDB, PostgreSQL and SQLite. The matching schema in SQL/ is applied automatically by the Roundcube plugin installer on first install.

Upgrading

Schema changes ship as versioned migrations under SQL/<driver>/. After updating the plugin, apply them from the Roundcube root:

bin/updatedb.sh --dir=plugins/f2b/SQL --package=f2b
