Arrange the standard steps for validating a newly configured site-to-site IPsec VPN tunnel in order, beginning with initiating end-to-end traffic and concluding with firewall policy confirmation.

### The order 1. **From Site A W1, ping 172.17.20.10**: The lab begins testing internal reachability with a ping to Site B's W1. 2. **Confirm successful replies**: Replies show that the end-to-end test succeeded. 3. **Check that IKE and IPsec status indicators are green**: The lab says to check the tunnel indicators after successful ping tests. 4. **Inspect the completed W1-to-W1 traffic log and verify Allow and the matching VPN rule**: The log confirms the policy decision and the rule that handled the session. ### The concept Testing moves from user-visible connectivity to tunnel status and then policy evidence. A successful ping alone does not show which rule allowed it, so the traffic log provides useful confirmation of the policy match. ### Terms - **ICMP**: Internet Control Message Protocol. Supports diagnostic messages such as ping. - **IKE**: Internet Key Exchange. Negotiates VPN security associations. - **IPsec**: Internet Protocol Security. Protects IP traffic. - **W1**: The workstation named condorID-W1 in the lab. ### Remember Test connectivity first, then confirm tunnel state and the logged policy decision.
