Use Terminal Route Add Commands

[dave_sky]

Have anyone successfully used tried to route traffic to multiple interfaces? For example, routing all internet traffic to the wireless connection, while routing only 10.0.0.0/8 traffic to the Ethernet. I doesn't appear to work the way it should. Here is what the netstat -nr command shows after using route add command to add the various routes:

192.168.120.255 ff:ff:ff:ff:ff:ff UHLWbI 0 5 vmnet8

I can ping the various gateways but cannot route traffic to internet through 192.168.40.250, for example. If I disconnect the Ethernet connection, the traffic is then re-routed. Any thoughts?

Whatever interface is at the top of the list in Sys Prefs is the gateway that is used.

As for modifying the routes I have not tried.

Please repost if you make headway as I would be interested.
