RouterOS Beginner Basics

Hey,
Since some time I found difficulties with Net on Mikrotik.
In log once a day i can find this error : eoip-tunnel1 : bridge port received packet with own address - probably loop as source address (x), propably loop

Any advice what it can be ?

No,

share both config.

most likely admin error on config, the router is not a sentient being.

asdas

(you sure?)

6

Looking at the MAC addresses, you probably restored a backup from another device?

I don’t really know whats going on …
I started work here few weeks ago.
It’s hard to tell but i think best way is to do all from beginning

That will likely solve it, as long as you do not paste that export back again.
Alternatively you can try changing (or just removing) the MAC address settings seen in the config.
That will make them fall back to defaults which are the device-unique MAC addresses assigned during manufacturing.
Then you should not see packets from other devices with MAC address same as locally configured.
