Hi all,
I am trying to setup up a site-to-site connection from my local network to my AWS VPC to access an MS SQL Datebase through RDS Proxy.
My local network is: 10.1.1.0/24
My VPC Network is: 192.168.0.0/22
Inside this I have an RDS Proxy pointing to my database. This Proxy has the IPs 192.168.2.1/24 and 192.168.1.1/24
When I try to connect to the database from another EC2 instance inside my VPC all is working and I can use the proxy.
But when I try to reach the database from a host inside my local network I get an error, that the SQL Host can't be found.
On the local side all Firewall and Routing should be set up fine. Iin Firewall logs I can see outgoing traffic to the AWS, but there is no traffic coming back.
So I would suspect that I am missing something on AWS side. Is there anything more I have to setup?
Best regards

I checked the security groups. For testing I allowed Port 1433 on 0.0.0.0/0 but that does not help. NACL's allow everything from 0.0.0.0/0 (inbound and outbound).
From outside the VPN I can resolve the DNS and get back the IP 192.168.1.1. Inside the VPN it is blocked by firewalls, therefore I have to use the IP directly. I would expect that doesn't matter anything if I use IP direct.
Can you clarify.
