I added to rsyslog.conf a lines
ModLoad imudp UDPServerRun 514 local0.* /var/log/dlink.log
With tcpdump I can see the packets from dlink somethimes local0 somethimes local1 even local2. Nothing appeared in /var/log/ dir. Which steps i missed to log my network device? I tried local1 local2 point to the same log file, but this didn't make the trick.
