Do any of you know the format for blacklisting an entire subnet in the ASBCE 7.2? I have tried using something like w.x.y.z/24 and other formats for example but that isn't working. Apparently these hackers buy an entire subnet of addresses.

As far as I know, only URIs in plain or regex form can be defined in the security rule blacklist. Where in the SBC are you trying to define blacklisted subnets?Meridian IT - Senior Engineer

Blacklisting individual IP addresses work but hackers usually pull from an entire subnet so the addresses keep changing.Comment

What is the IP address range you are trying to block?
If I wanted to block 77.247.110.62 which is an IP from the Netherlands that has been hitting my one of my SBCEs, I might go ahead and try and use 77.247.110.0/24 to cover the range of 77.247.110.0 - 77.247.110.255. Have you tried it that way yet?Comment
