Firewall issue with Aliases / Ranges
Stef last edited by
I have a firewall rule which allows incomming mail from specific domains only.
The easy way I've added all relevant ip addresses,
first I tried adding a range 18.104.22.168 CIDR 24 which should be all ip addresses from 1 to 255
However when I do specify individual addresses it works fine, otherwise these ip's are blocked as show in the 3 images,
Alias is an overview of all ip's in the range.
Disallow is specified in /24 range but not specifically
Allow is specified specifically
Is this a bug or am I doing something by specifying the /24 range ?
