How do i tell if all traffic is going though the vpn?

Solution 1:

If you're on windows then start a dos window and run the tracert command.

e.g. tracert www.google.com

You can also use an IP address instead of a DNS name.

If you're on Linux you can do the same with the traceroute command.

With both utilities you should hopefully get a trace of the route that packets take to reach the destination. You'll be able to tell if it's passing through your VPN gateway.

Solution 2:

On OS X, I use this, and it shows the interface as either en0 or utun0:

ex:

$ route -n get website.thatshouldroute.com
