Module ngx_http_access_module

Example Configuration
Directives
     allow
     deny

The ngx_http_access_module module allows limiting access to certain client addresses.

Access can also be limited by password or by the result of subrequest. Simultaneous limitation of access by address and by password is controlled by the satisfy directive.

Example Configuration

location / {
    deny  192.168.1.1;
    allow 192.168.1.0/24;
    allow 10.1.1.0/16;
    allow 2001:0db8::/32;
    deny  all;
}

The rules are checked in sequence until the first match is found. In this example, access is allowed only for IPv4 networks 10.1.1.0/16 and 192.168.1.0/24 excluding the address 192.168.1.1, and for IPv6 network 2001:0db8::/32. In case of a lot of rules, the use of the ngx_http_geo_module module variables is preferable.
