When connected to VPN using the built-in VPN service, is all my internet traffic routed through the VPN connection?

I have configured a VPN service using only the built-in options from OS X. I have configured it as follows:

• Interface: VPN


• VPN Type: Cisco IPSec


• Service name: ...

I don't have any settings under Advanced, so I have entered no DNS Servers, no Search Domains, and no Proxie Servers or Proxy Configuration file for any of the protocols.

When am I connected to this VPN, does all my traffic go through the VPN connection? In other words, if I am using a messenger, searching on Google, sending email or browse the web, can the provider of the VPN service see all my traffic?
