I am familiar with the route add default gw command in Linux to add a default gateway, but this doesnt work on Mac OS. I cant find any appropriate example in the route manual. Can anyone help me the command.

is it possible to bind a route to a network environment ? – YoshiBotX Nov 28 '14 at 12:23

If you are intent on using route the man page for route will show you it's the same as most BSD route commands. You may need ip6config (and man page) as well if you care about IPv6 routing.

The "mac" way is to set it from the System Preference pane under network and is preferred over using unix commands since it honors location changes and other events such as a reboot.

manual TCP/IP configuration

But in that very screenshot, you will get an error message if you press "OK" since this method also require you to set a manual IPv4 Address, which might not be desirable. – Fuzzy76 Apr 14 at 12:28
@Fuzzy76 Yes - if you manually set an unworkable network, your network will not work. The Router here is fine though since that is the default gateway equivalent to the answer on how to change things from the command line. – bmike Apr 14 at 13:16
