Debugging with an AWS RDS database

Simon TJun 24 2026

I've never successfully got debugger working on the VSCode plugin. It's one of the 2 things that keep pulling me back to OG SQL Developer (the other being around scheduler stuff). Today I cracked and put aside an hour to see if AI could get me through. Naturally it was very enthusiastic and full of solutions but finally I gave up. To make sure it wasn't all wasted though I asked it to summarise exactly what defeated us…

Because the VS Code extension strictly relies on JDWP (requiring an outbound database-to-client connection) and doesn't support legacy _DBMS_DEBUG_ (which keeps traffic over the inbound Port 1521), is there a known configuration to bypass AWS Client VPN Source NAT so an RDS instance can route traffic back to a VPN client? Or is an AWS Site-to-Site VPN / Direct Connect strictly required for this extension?

Am I flogging a dead horse here or is this always going to be a non starter? I've got full control over my local machine and ACL type stuff on the DB but probably can't be making any RDS level network changes
