Translations:Set block/226/en

The default is 30 which is a safe value for everyone. Be careful if drastically lower this. DNS lookups, ident lookups and the handshake may take more time than you may think in some cases. You can probably set this to a value like 20 if you like. However, if you set this setting too low then you risk locking everyone out when for example your DNS server is a little slow (eg: under attack).
