Multi cloud VPN connection to RDS

Question

Hi, i've created a VPN connection from GCP to AWS following this guide: https://blog.searce.com/connecting-clouds-aws-gcp-771eb25a2dc3 Then i've created a vm con GCP and i've tested the connection to AWS. On AWS i've a Elasticache instance which i can connect without problems, but if i try with the RDS instance i've:

> ERROR 2002 (HY000): Can't connect to MySQL server on '...' (115)

Security group and firewall rules seems right in AWS and GCP. Both Elasticache and RDS instance are in the same VPC and the same subnets group. I also tried to set "Public access" on RDS without results.

Some suggestions on that?
Thanks

Answer

Hi.

Since it's on the same subnet as Elasticash, I don't think there's a network problem.

[Confirmation on AWS side]  
Are the information such as the inbound port and source IP address of the RDS security group correct?

[Confirmation on Google Cloud side]  
Can I create Cloud SQL for MySQL within Google Cloud and connect from a Google Cloud virtual machine?
