Need to block IPs use APF, how ?

[jameshsi]

Hi!
I just want to block a whold class C of a IP, how to do that in APF ?

For example, I need to block 163.29.*.*

What should I put into the /etc/apf/deny_hosts.rules ?

You would need to use CIDR notation:

Class C it's not XXX.XXX.*.*

It's XXX.XXX.XXX.* = XXX.XXX.XXX.0/24

You can use 163.29.0.0/16 for entire 65536 IPs - Class B (163.29.0.0 - 163.29.255.255)

if you are not sure how to calculate the CIDR, one useful site is http://www.dnsstuff.com/ on the CIDR/netmask
