Apple - add a permanent static route in high sierra
I suggest to use networksetup which works persistent and also in separate network locations.
First, open your terminal of choice i.e. iTerm2.app or Terminal.app
- list your network locations:
networksetup -listlocations
- choose your desired network location:
sudo networksetup -switchtolocation <locationofchoice>
- list "devices" called networkservices
networksetup -listallnetworkservices
- list persistent routes on "device" of choice i.e. "Ethernet"
networksetup -getadditionalroutes Ethernet
- add your route to "Ethernet"
sudo networksetup -setadditionalroutes Ethernet 192.168.1.0 255.255.255.0 10.0.0.2
- list persistent routes on "Ethernet" again to check
networksetup -getadditionalroutes Ethernet
To see all commands:
networksetup -help or
networksetup -printcommands
Hope that helps ;)
