Add static route on OS x, need the following steps

  1. Find the network service which can access gateway
    mac-mini:~ ladmin$ networksetup -listallnetworkservices
    An asterisk (*) denotes that a network service is disabled.
    Bluetooth DUN
    *Bluetooth PAN 2
    mac-mini:~ ladmin$ networksetup -getinfo LAN
    Manual Configuration
    IP address:
    Subnet mask:
    IPv6: Automatic
    IPv6 IP address: none
    IPv6 Router: none
    Ethernet Address: 00:1f:5b:33:1d:75
  2. set additional gateway on the network service
    mac-mini:~ ladmin$ sudo networksetup -setadditionalroutes LAN
    mac-mini:~ ladmin$ networksetup -getadditionalroutes LAN
  3. Check the route list

    mac-mini:~ ladmin$ netstat -rn

    Add more routing paths:

    iso@isoAir:/dev$ sudo networksetup -setadditionalroutes “Ethernet Pantalla Trabajo”
    iso@isoAir:/dev$ sudo networksetup -getadditionalroutes “Ethernet Pantalla Trabajo”
