Each Magic WAN Connector connects to the same two ISPs using dual uplinks, and automatically creates one IPsec tunnel per WAN port. This requires each ISP to support multiple ports on their on-site Network Termination Unit (or their CPE, if there is one present). In this HA deployment there are four tunnels in total, two per Connector, while traffic can be load-balanced between the two tunnels on the active device. When either the active Connector, or its IPsec tunnel go down, the other Connector takes over and propagates traffic, holding the active role until it fails (preemption is not used to avoid unnecessary failover delays).

In this example, the organization wants Cloudflare to protect all Internet web traffic (HTTP/HTTPS), while the rest of the traffic flows out via the existing firewall. The latter could be traffic towards existing VPNs, or non-web traffic exiting the site, but protected by the on-premises firewall. This method could take the advantage of local device policy-based routing (PBR) capabilities, for example:
