Arrange the steps a router or firewall takes to send traffic to a remote LAN across a route-based site-to-site VPN, from initial route lookup to final transmission.

### The order 1. **The destination is identified as belonging to the remote LAN**: the firewall compares the destination with its routing information. 2. **The firewall uses the route to select the tunnel interface**: the route identifies the VPN path for that remote subnet. 3. **The traffic is sent through the protected tunnel toward the peer**: after path selection, the VPN carries the traffic to the other site. ### The concept Routing selects an egress path based on the destination. A tunnel route only helps when the firewall has a matching route for the remote network. Once selected, the tunnel provides the protected path between peers. ### Terms - **LAN**: Local-Area Network. A network serving devices at one site. - **VPN**: Virtual Private Network. A protected connection between networks. ### Remember Identify the remote destination, select its route, then forward into the tunnel.
