Dynamic interface list members added automatically

Hello team!!!

I just see, in a Mikrotik, LAN interfaces are being added dynamically in the interface list called “WAN”.
What could be the setting that add these interface list members?

Thanks in advance.

Detect internet …

Hello team!!!

Thanks for your answer mkx!!! I didnt know “Detect internet”
I couldnt figure this out how to disable this feature, I just turned all to static:

/interface detect-internet
set detect-interface-list=static internet-interface-list=static lan-interface-list=static wan-interface-list=static

Is this enought?
I cant see why is this feature usefull. If I have many Interface lists defined manually, why could I want to change what I defined initially?

I have no routes to 8.8.8.8
I have only one dhcp-client in a LAN Interface, added by “Detect internet”
Still does not know why these LAN interface were added in the wan list.

Thanks in advance.

Many people wonder about perils of detect intetnet. To disable it, it’s best to set all items to “none” (without the double quotes).

Thank you mkx!!!
I just set all items to “none”! Will see
