I've been trying to setup some Draytek 3900s to send their Syslogs to the PRTG Syslog Sensor. I can get most of the logs through, but it seems to be completely omitting the firewall logs for some reason.
I've tried both with the Syslog sensor setup on the probe device as a sort of catch-all, as well as directly on one of the router devices. I've also changed the Syslog port on one router to 515, mostly to isolate it from other traffic. I have also tried setting the Syslog settings on the Draytek to remote only and "both" (Remote and local), tried changing which entries are sent, but no matter what my PRTG server doesn't show the Firewall syslog entries.
The sensor itself is setup with just default settings, which to me seems to accept all syslogs so I'm at a bit of a loss. Has anyone managed to pickup Firewall syslogs from Drayteks using the PRTG syslog sensor?
