Hi,
recently i stumbled over a tremendous amount of Log entries:
kernel: IPv4: martian destination 0.0.0.0 from XXX.XXX.XXX.XXX , dev eth0
I tracked the Ip down to a tasmota esp8266 device. Alle Networ settings were correct. However, the Syslog logging was switched to something > 0 and no host was given.
So every message went to 0.0.0.0 I suppose.
Switched logging to 0 and martian packets were gone.
The following debugging might help if this does not solve your issue:
tcpdump -i eth0 host XXX.XXX.XXX.XXX
The following was logged: IP XXX.XXX.XXX.XXX.55246 > 0.0.0.0.syslog: SYSLOG local0.info
