Hello,
Apologies in advance for the repeat as I am sure this has been covered extensively, but couldn't find it in the history.
I set up my DS220+ NAS with OpenVPN to access it when traveling.
I have been testing it from work (NAS is at home), and even within a few yards from my house my transfer speed is "capped" somehow at 2.3Mbps, super slow.
I have tested my speeds at home and it's well above that (200/300Mbps), without OpenVPN.
My settings:
  • DS220+ / DSM 7.1, SMB 3 protocol, ethernet connection to TP link mesh router, ethernet connected to ISP router
  • Both routers set up with Port forwarding
  • I followed the settings from SpaceRex,

    View: https://www.youtube.com/watch?v=vBXlZf7gSwc, with the latest patch and it connects fine (but super slow)
  • VPN server: Encryption is set to AES-256-CBC (no option to turn it off)
  • ISP speeds, not the super top ones but still: download 80Mbps, upload 20Mbps; I assume I would in that case get 20Mbps connection, correct? Still enough to stream & work with.
  • I'm a MAC user, running Laptop on IOS 13.6, in case

Any indication about settings on my NAS, router, OpenVPN, etc... which could help with the speed?
Thank you in advance for your expert advices.

Welcome

When inside a tunnel your speed will be maxed at your VPN servers upload speed. So 20Mbps will be your max. What client are you using with your MacBook? Have you tried running with Viscosity client (google it a bit)?

Also, what are you trying to do over VPN? SMB transfers? If so, have you tried to disable the SMB signing on the macOS end? See if that helps. Those 2.3Mbps speeds you are getting, what are you using to get those results?

Also are you inside a full tunnel, or split one? How is your VPN configuration set? Try and give as much information as you can, and I am sure people will share their experience with you on the matter. Also what speeds are you getting on the destination side? Are you testing via 4G mobile, some corporate connection, wifi in a coffee shop or what?

Hello Rusty,
Thank you for the insight.
I'm using OpenVPN, and it shows on its page the actual download/streaming/transfer speeds.
While testing it from work, it would cap at 2.3Mbps (or Mb/s) (350Mb/150Mbps speeds there).
I am abroad on 4G and the speed now is a meager 450Kbps (or 450Kb/s).
I will try again once back on proper wifi.
I'm afraid I'm not familiar with split tunnel, where can I check this?
The VPN is set on UDP protocol, IP dynamic address set with DDNS
What else?
