It really depends. There are different ways of implementing VPNs.

* Split tunneling- All non-VPN traffic is blocked.
* Transparent tunneling- All traffic goes through the VPN connection,
then through the corporate firewall to it's intended destination (and
back).
* Don't care- VPN traffic is tunneled, regular traffic goes whereever it
needs to go...
