Hi Gruens,
Thanks for your inputs. Here is what I'm planning to setup, install Pfsense as firewall in all of the sites and configure the OpenVPN client/server setup. The subnet is a trusted subnet, and the scenario would be e.g., clients on site 1 will able to see/share files on the Head Office subnet and vice versa.
