I am troubleshooting connections to our 12.1 CES ESA by setting up an Injection Debug Log. The connections come from a range of ip's, for example say they are from 136.228.192.0/18. I have tried specifying CIDR format, and a range like 136.228.192.0-136.228.192.255 but it keeps giving an error message The allowed hosts information must be IP fragments, addresses or ranges, or hostnames, separated by commas. Any ideas?
