can we change default gateway and interface in mac through commandline

We can see default gateway and interface of MAC by using following command

route -n get default

I know that this is possible in linux and can be achieved by following commands

route change default -interface $INTF route change 192.168.0.0/16 -interface $INTF But these are not working in MAC. My objective is to change the Default Gateway and interface.

Solution

  • The networksetup utility should be able to do what you want.

    For example, to manually set up the standard Ethernet interface with an IP of 192.168.100.100, subnet of 255.255.255.0 and gateway of 192.168.100.1:

    networksetup -setmanual "Ethernet" 192.168.100.100 255.255.255.0 192.168.100.1
