I have two networks spread across two locations, the current setup has a direct connection from the Primary site to the Secondary passing through the ISP with our router setup, we are the 2nd site's internet breakout, so all traffic comes out from our FW. In the future, the 2nd site will be physically relocating to a new building, potentially with its own internet breakout. I am looking for the best option to connect this site back to our for clinical application access, whether that would be a Site-to-Site VPN with split tunneling or BGP peering.
Can I get some suggestions? I appreciate any help you can provide.
