want to confirm my gut on a design question a customer gave me.
Looking at doing SD-WAN using either Meraki or Viptela configurations.
Customer also has firewalls at their main location for general firewall work and VPN for users.
My thinking is that these firewalls would stay in place for the corporate Firewall work to the Internet and for VPN connections for users and the SD-WAN concentrators would be in be in parallel connections to the Internet.
