Metric on connections and magic 20000 value added
I have 3 types of network connection and I set manyally metric for each connection:
- LAN cable, metric = 1 -
enp0s31f6, - WiFi, metric = 100 -
wlp2s0, - 4G/LTE modem, metric = 1000 -
wwp0s20f0u8c3.
The reason for setting of metric is that I want to prioritise my connectivity based on the list above (the modem connection is metered). I also set autoconnect priority for each connection but according to KDE#394364 this will not work as I expected so that’s why I tried to go the way by setting of the metric.
When each connection is activated, the system adds a strange value of 20000 to the metric.

This value 20000 is not added always, or to be more precise, it gets changed after some time to the value which I set for the particular connection.

Any idea why this is happening?

This is the behavior of Network Manager from version 1.8, see commit: https://github.com/NetworkManager/NetworkManager/commit/6b7e9f9b225e81d365fd95901a88a7bc59c1eb39
It says:
This makes it possible to retain Internet connectivity when multiple
devices have a default route, but one with the link type of a higher
priority can not reach the Internet.
