I'm seeing an increasing amount of traffic from our PRTG server to Level3 Communications Inc IP addresses as of November last year; I'm assuming for the moment that this is part of what appears to be a relatively recent working relationship with Level 3 as a CDN? This traffic is currently blocked by our firewall.
Are you able to provide FQDNs (wildcard if necessary) for the destinations so that we can authorise this traffic? I can find no listing for it elsewhere in the knowledge base or other documentation.
Hello,
Thank you for your KB-post.
For this kind of issues, we need to check the log files from your PRTG.
Please open a support ticket to us and we will continue troubleshooting there. Thank you!
