I cant seem to use CIDR notation to specify an entire IPv4 network while creating a firewall rule, its saying its not a valid source for some reason, I have seen other people do this with no issue before. Am I inputting it wrong or doing something wrong?
So, I was able to get this to work, by exporting the firewall rules and editing the JSON but it looks like specifying CIDR in the GUI is not working.
Thank you for the post! This has been resolved.
