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?

Edit:

Here are the default entries in my routing table (output from netstat -r -n):

Routing tables

Internet:
Destination        Gateway            Flags        Refs      Use   Netif Expire
default            192.168.1.1        UGSc           10        0     en1
default            gway#5             UCSI            0        0   utun0


There are a whole bunch of IP-addresses that list specific gateways. I checked some of those IP-addresses, and they are related to the network that I use the VPN for.

Does the fact that the first default is my own modem/router mean that in fact not all internet traffic passes through the VPN?
Yup when using the VPN everything goes through your VPN.
