On OS X 10.11 (El Capitan), with the Cisco Built-in VPN client, I would like to configure the route table in order to have the following thing :

  • subnet traffic goes through the VPN
  • everything else ( my local network, and all the internet) goes through en0, and not through the VPN

Is there a way to configure it with some tricky route add|change|delete commands? Moreover is there a way to run this commands every time I connect to the VPN.


For the first part (how to split traffic), I had the solution with the two following code lines

sudo route add -net <REMOTE_SUBNET> -iface utun0
sudo route change default <LOCAL_GATEWAY_IP>
