OpenVPN/VM Security Advice


unbroken

Recommended Posts

I'm running an OpenVPN server in a Fedora 21 VM on unRAID 6, and I have two ports (500 and 4500 UDP--both specifically for OpenVPN) being forwarded from my router to the VM. If, somehow, the Fedora VM gets compromised, will unRaid then become susceptible to [remote] attacks? To my understanding, VMs are isolated from the rest of the OS, but my concern here is mainly about the ports being forwarded to my unRAID box while it's acting as the hypervisor. My router has built-in support for OpenVPN as well, but  it doesn't performe nearly as well for me on my mobile devices as the instance of OpenVPN I'm running in the VM does. I've also considered running an OpenVPN docker. Is this, more or less, as secure as running it in a full blown VM?

 

I'd like to limit the ports being forwarded to my unRAID box as much as possible but still have remote access to my LAN/SMB shares/unMENU (is this the official name for unRAID's webGUI? I've seen it mentioned a few times in the forums.) Any advice would be greatly appreciated.

Would an OpenVPN docker help. No, it would have the same security concerns... more or less.
