Hi,
Just read your project description, regarding the Internet Access & VPN related configuration you require. In my opinion, yes we can have the normal internet traffic routed towards the Normal Internet connection while route certain traffic towards the VPN. Further, in my opinion & experience I do not believe that you can route traffic between the Internet and VPN while using applications such as Google Chrome and internet Explorer, unless you have some custom tool that edits the routing table of your system as per your needs.
I believe to find this a small task that will not require much to do. We can discuss on the chat for the rest.
I am Bilal, a Network Specialist and Consultant for the past 8 years with experience of designing, implementing, migrating and troubleshooting various types of network (Enterprise, Telco, ISPs).
Feel free to contact me.
