How can I configure my VPN client on OSX as a split tunnel? I don't want all my traffic to travel over the (slow) VPN. Surely there must be a way to add a default route that bypasses the VPN.

I am using the Cisco VPN Client version 4.9.0.1.0180 on OSX Snow Leopard.

This is configured on the server side by your administrators.

I'm connected via a Cisco VPN client and only traffic destined for our servers goes through the VPN interface. All other traffic goes straight out my internet connection without passing through the VPN.

The easiest solution (from a technical point of view) is to ask your administrators to configure the connection for split tunneling. That solution might not be easy (or even possible) from a political point of view.

Yes politically, a split-tunnel is dead in the water. I am looking for a work-around. In a Unix(like) environment, I can't imagine it would be impossible to fix up the routes after the fact. –  Caffeine Coma Sep 21 '09 at 19:12
    
Yeah, I imagine with the right incantation of "route add" and "route change" commands, you'd be able to specify how traffic should go. You know about "netstat -r" to show route tables on OS X? –  Doug Harris Sep 21 '09 at 20:26
    
Well it looks like I have two default routes- first one being the VPN, and then the other one being my usual default. I'm not sure how to give one precedence over the other. I tried deleting and then re-adding the "real" default, so that it appears above the VPN default, but then all my traffic goes no where. –  Caffeine Coma Sep 21 '09 at 22:58
