Access Rules


#1

Hello. I would like to add subnets to the whitelist in the firewall in order not to blocking ip addresses from payment gateway. These subnets contain the following masks /27, /25/. But i am only able to add /16 and /24 masks. How can i add my needed masks, given to me by payment provider?

You’ll have to go with /16, as it’s less restrictive and will still include those subnets. /16 covers 123.456.xxx.xxx, and /24 will include 123.456.789.xxx

For /25 and /27 networks a /24 definition should actually suffice.

On a related note though, I never understood that restriction :confused:

Oops, that’s right. /16 sounded better in my head, and I even mapped it out and still didn’t catch that.
