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, by the result of subrequest, or by JWT. 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.

Directives

Syntax:	`allow address \| CIDR \| unix: \| all;`
Default:	—
Context:	`http`, `server`, `location`, `limit_except`

Allows access for the specified network or address. If the special value unix: is specified (1.5.1), allows access for all UNIX-domain sockets.

Several allow directives can be specified on the same level. These directives are inherited from the previous configuration level if and only if there are no allow and deny directives defined on the current level.

Syntax:	`deny address \| CIDR \| unix: \| all;`
Default:	—
Context:	`http`, `server`, `location`, `limit_except`

Denies access for the specified network or address. If the special value unix: is specified (1.5.1), denies access for all UNIX-domain sockets.

Several deny directives can be specified on the same level. These directives are inherited from the previous configuration level if and only if there are no allow and deny directives defined on the current level.
