Macbook Pro unable to use the internet while connected to IPSec VPN Short Question
Is there something I am missing when setting up a Cisco IPSec VPN connection that redirects all traffic over the VPN?  

Background
When I am connected to the VPN, I can browse our company's intranet with no problems, but when I try to go out to say www.google.com it times out.  Another co-worker is having the same problem on his MBP as well.  The VPN client we use for our Windows machines is Shrew Soft talking to a pfSense router, which works like a champ.

IPSec connections to Cisco routers are only allowed split routing based on the configuration of the router.  I don't know what kind of router you are connecting to,b ut an example is shown here.  Basically whomever is running the router would need to configure it to allow this behavior.
