I am a beginner on this. When I perform a netstat -nr.
I need to change
default 192.168.1.254 default link#4
default link#4 default 192.168.1.254
What command to swap this sequence?
Why don't you go to System Preferences -> Network to change it manually, with GUI.
The first thing to try with multiple en0 / en1 / en2 on a Mac OS would be to explicitly set the service order in the network preferences.
You can’t change the order of virtual private network (VPN) connections because they already take priority over non-VPN connections.
Choose Apple menu > System Preferences, then click Network.
Click the Action pop-up menu , then choose Set Service Order.
Drag services into the order you want.
Click OK, then click Apply to make the new settings active.
