I know I can put my DS918+ IP through a VPN, using my router, whilst letting everything else in my network run on the WAN connection. However I find that when I try to remotely stream media from my NAS on Plex or DS Video, it is very slow and laggy due to not being able to port forward. The VPN internet speed is usually around 30-40 mbps, so I don't think the VPN itself is the problem. On research, you can't run port forwarding on expressVPN via manual configuration, unless you have the App on your router (Synology doesn't support at present). Is there a way of putting JUST Download Station through a VPN, but nothing else?
