Using 'deny all' instead of an IP address.

Using 'all' which allows everyone.

Using 'localhost' which is not the target IP.

The allow directive followed by the IP address permits access from that IP.

💡 Hint

Common Mistakes

Using 'allow all;' which allows everyone.

Using an incorrect IP address.

Omitting the 'deny all;' line.

To allow only one IP, use allow with that IP and then deny all; to block others.

💡 Hint

Common Mistakes

Using 'deny 0.0.0.0/0;' which is invalid in this context.

Using 'allow all;' which allows everyone.

Using 'deny localhost;' which does not block all others.

Use allow 192.168.0.0/24; to allow the subnet and deny all; to block others.

5fill in blank

hard

Fill all three blanks to allow 10.1.1.0/24 subnet, deny 10.1.1.100, and deny all others.

Nginx

deny [1];
allow [2];
deny [3];

Drag options to blanks, or click blank then click option'

A10.1.1.0/24

B10.1.1.100

Call

Dlocalhost

💡 Hint

Common Mistakes

Reversing the order of allow and deny directives.

Using 'deny localhost;' which does not block all others.

Omitting the final 'deny all;' line.

First deny the specific IP, then allow the subnet, and finally deny all others.
