I currently receive this message on 2 of my 3 OpenWrt routers.
br-lan: received packet on lan1 with own address as source address (addr:12:34:56:78:9A:BC, vlan:5)
I have checked similar posts about this and all stated that there is a loop somewhere in the network. Which isn't the case in my network and also no device is spoofing the MAC addresses. I have the following network setup.
I have checked the Routers and all have the same MAC Address for the same interface. Now if I want to access the MGMT interface on one of my AccessPoints, I will connect via WiFi on the Unmanaged LAN interface, will be routed to the Main router inside the LAN VLAN (1), will then be routed back to the AccessPoint inside the MGMT VLAN (5). As it is intendend.
How do I get a package at one of the APs saying it has its own MAC? All the Ethernet Frames should be rewritten with the MAC address of the Main router when they get processed by it.
Can anyone help me with this?
FYI: I have this since I upgraded to 21.02.
