Hello I'm sorry I have the same problem I followed all the instructions to install OpenVPN on my EC 2 instance (Amazon) but when I connect my client to the server, it doesn't give me the server IP in whatismyip.com but my client IP :/ So there is no routing and I think it's the same problem you discussed in this topic.
Hope you can explain what Vertixo explained ? 🙁
