How to add Nginx proxy configuration to allow only internal IP access

location / {
index index.jsp;
proxy_next_upstream http_500 http_502 http_503 http_504 error timeout invalid_header;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
deny 192.168.1.1;
allow 127.0.0.0/24;
allow 123.56.0.0/16;
allow 172.16.0.0/16;
allow 10.170.0.0/16;
deny all;
}

The above is my location configuration list

Note:

1. You must add an IP address when denying , otherwise it will jump directly to 403 without further execution; if the 403 default page is under the same domain name, it will cause an infinite loop of access;

2. Allowed IP segments

Arrange from the smallest to the largest segment allowed to be accessed, such as: 127.0.0.0/24

The following can be: 10.170.0.0/16

24 represents the subnet mask: 255.255.255.0

16 represents the subnet mask: 255.255.0.0

8 represents the subnet mask: 255.0.0.0

3. deny all; ending

Indicates that all other parameters except the above allow are prohibited
