It has (something) to do with 'metric':

Routing has to do with networking, that's why the basic rules apply to
both linux and windows.
The implementation of that rules, and how to apply those rules, is
another story.

Ok, I understood. The default gateway will go with the lowest metric.

In my case I have:
netstat -rn
https://justpaste.it/2c9m8
Route active:
network address Mask Gateway Interface Metric
0.0.0.0 0.0.0.0 192.168.42.129 192.168.42.165 10
0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.10 25
So the metric of gateway 192.168.42.129 is smaller than 192.168.1.1 ,
so the default gateway is set to 192.168.42.129 ( it's the usb tethering).
I'm looking from use 192.168.42.129 as default gateway to go on
internet, and 192.168.1.1 ( the dsl router) to use only 192.168.1.1/24 (
internal lan network).
How may I do it with windows using "route" command from cmd prompt ?
Thank you very much.
