Diagnose whether traffic between your VPC and an on-premises service over Dedicated Interconnect is being dropped by firewall rules or by routing.

Network Intelligence Center Connectivity Tests simulate the data path between two endpoints, including firewall rules, routes, and network configurations, providing a definitive answer on whether traffic is being dropped by firewalls or routing. Network Topology visualizes network components but doesn't perform live path analysis. VPC Flow Logs show accepted or denied connections but don't differentiate between firewall or routing drops without further analysis. Traceroute helps identify routing paths but doesn't directly test firewall rules or provide a comprehensive diagnosis for both issues simultaneously.
