 **black-/whitelist handling:**  
@@ -225,6 +226,9 @@ banIP supports a local black & whitelist (IPv4, IPv6, CIDR notation or domain na
 Unsuccessful LuCI logins, suspicious nginx request or ssh login attempts via 'dropbear'/'sshd' could be tracked and automatically added to the local blacklist (see the 'ban_autoblacklist' option). Furthermore the uplink subnet could be automatically added to local whitelist (see 'ban_autowhitelist' option). The list behaviour could be further tweaked with different timeout and counter options (see the config options section above).  
 Last but not least, both lists also accept domain names as input to allow IP filtering based on these names. The corresponding IPs (IPv4 & IPv6) will be resolved in a detached background process and added to the IPsets. The detached name lookup takes place only during 'restart' or 'reload' action, 'start' and 'refresh' actions are using an auto-generated backup instead.
   
+**whitelist-only mode:**  
+banIP supports a "whitelist only" mode. This option allows to restrict the internet access from/to a small number of secure websites/IPs, and block access from/to the rest of the internet. All IPs and Domains which are _not_ listed in the whitelist are blocked. Please note: suspend/resume does not work in this mode.
