@bmeeks said in How do I find this device?:
@gregeeh if you do not want this traffic filling up your logs, create a rule near the top on your LAN interface that has any as the source, UDP as the protocol, ff02::1 as the destination address and 10001 as the destination port. Set the rule to drop but not log.
Right now that traffic is hitting the firewall's default deny rule and that rule is logging the dropped packet. By inserting your own rule up higher in the chain, the packet is "handled" by your rules and thus never gets to the default deny rule (which is at the bottom of the rule chain).
Most helpful. Thank you.
