Introduction:
Oracle
Cloud Infrastructure (OCI) provides Bastion as a secure and convenient way to
access private resources without exposing them directly to the internet.
Recently, while trying to connect to a Windows Server 2012 instance via RDP
through a Bastion host, I encountered connection issues. Despite setting up SSH
port forwarding, the RDP session would not establish. This experience
highlighted an important consideration: while Bastion is ideal for many
scenarios, there are situations where it may not work, and OCI’s Console
Connection (VNC) can be a reliable alternative.
In this blog, I’ll walk you through the root cause of the Bastion failure, explain why it occurs, and guide you on how to use Console connections to access Windows instances.
