Allow whole class C IP range. 12.162.0/24.0/24 doesn't work

Post by brilliant »

Hi guys,

I am trying to allow a whole class C IP but the quaded IP I have entered doesn't work.
I wanna allow IPs that are 12.162.XXX.XXX

Here is the setting: 12.162.0/24.0/24

Am I missing something???

Forgive me if I'm wrong but 12.162.0.0/32 seems like it allows only 12.162.0.XXX
I basically need to allow IPs beginning with 12.162.

You need to use valid CIDR notation. In this case it would be 12.162.0.0/16. See:
