Communication through Site to Site VPN Tunnel

0

I have the following scenario, an ECS cluster running in a VPC with a VPN Site to Site with a static route, the tunnels are all UP which indicates that the configuration on the Firewall side is 100%, through this VPN I need to access an Oracle database on client side of the network. The route table is configured, as well as the ACLs and security groups. On the Firewall side, the range of Ips of the SubNets was released and even so, it did not participate in the communication with the other side.

please Perform a network connectivity test using a tool like traceroute, ping, or nc (netcat) from your ECS instances to the Oracle database server IP. This will help you understand if there's a specific network hop causing the issue.

    • Verify that the security groups attached to your ECS instances and the Oracle database server allow traffic between them. Double-check the ingress and egress rules to ensure that the relevant ports (e.g., 1521 for Oracle) are open for communication.
    • Check the route table associated with the subnets where your ECS instances reside. Ensure that there's a specific route entry for the remote network (where the Oracle database is located) pointing to the virtual private gateway.
