Hello, unfortunately it is not clear for me what do you want to achieve here. Please try to describe your use case in details. (There are good examples from the past on this list, where we could solve someones problem in a much simpler way, by knowing the overall goal, instead just answering the original question.) You might want to share: - OS and Syslog-ng version you are working with. - Configuration snippets (if you already have some working deployment) - (Since this is a network related question) Your network topology* - especially firewalls in place - Encryption required? - Reliability of the system/messages *You mentioned white listing. On what level do you want to filter out unwanted messages? (application or network) Thank you in advance, László Szemere ________________________________________ From: syslog-ng <syslog-ng-bounces@lists.balabit.hu> on behalf of Onur GURSOY <onurgursoygyte@gmail.com> Sent: Tuesday, August 20, 2019 13:34 To: syslog-ng@lists.balabit.hu Subject: [syslog-ng] IP WHITE LIST CAUTION: This email originated from outside of the organization.
