@RobertMEF I've been trying too with NordVPN and still no success....

Omada Controller

Version: 5.7.6

Build: 1.21.7 Build 20221206 Rel.58608

Router: ER605 v1.0 firmware 1.2.1

  @x-or 

From what I have found - it looks like we are waiting on an update to the router .  I have the ER605 .

Will this be supported for OC200 v1.0 for the new firmware update that was released yesterday? As of the v5.7.6, it does not support nordvpn for v1.0.

As of the last hardware controller firmware update (ER605 v2 ,2.7.7 Build 20221206 Rel.58608 Software v 5.7.6)I have been able to sucessfully logi into NordVPN. The connection has been reliable and stable. With that said I have not been able to connect to ExpressVPN. I suspect there are still issues. 
You can now enter your username and password as well as upload the certificate.

Good to hear you got it working .
I got a ER605 v2 and was able to get it connected to NordVPN .  However the speed is VERY slow .

I am on a 1 Gbps down and 235 Mbps up connection - I only get 12 Mbps down and up with the  VPN connected .
Using a Windows OpenVPN app - I can get 300 - 600  down and 230 up speed .   So the hardware must be very weak .

I'm not experiencing any obvious slowing. I get comparable speeds on my ER 605 v2 compared with other ways of connecting to NordVPN.  I do feel that that VPN connections are still buggy so that might be what is happening. Do you have the most up to date firmware on your equipment?

  @GAThrawn what instruction set did you use, thank you?!

  @GAThrawn 

Yes, everything is up to date .Have you dont a speed test while on the VPN ?
I would like to see what speeds you get .
