|Could you theoretically still get OpenVPN working on that DIR-615 rev D router? Hmmm, maybe. Perhaps by installing Entware (provided Entware even runs on Ralink chipsets, I'm just not sure). The challenging part is that you would need to install it on the JFFS partition (/jffs), assuming there's sufficient flash (iirc, Entware requires about 4-5MB for the core, plus the OpenVPN packages). If JFFS isn't possible, then either use external storage (e.g., a Windows share), or even under /tmp (the RAM drive, although the installation would NOT be persistent; it would need to be reinstalled and reconfigured w/ every boot!).
IOW, I can imagine this being possible, even though the firmware itself doesn't support it. It just has to be done through additional software.
All that said, I agree w/ bushant. That router is downright ancient (circa 2008) and woefully underpowered to support OpenVPN. Even if you could install OpenVPN on that router, it would be painful. You might get as little as 2-3Mbps over the VPN. Even modern day routers often struggle w/ VPNs, and why we advise that users who intend to support OpenVPN and want top performance get as powerful a router as possible.
