OK .

I finally got a VPN to work .  I reset the ER605 again and after I got it adopted, I tried the same old server configs / settings that I have already tried with no success .

Then I picked another free OpenVPN server, out of one of the several lists from which to choose, and downloaded that config file .

And when I tried it - wowwy wubbzy - it worked .  It was very slow .  I disconnected and then tried the windows client and it was also very slow .

Then I tried one of the others that I had already set up and it didn't work .  Then I tried the one that worked and it didn't work .  So, I messed around with trying different ones for a few minutes and then went back to the one that worked and tried it again and it worked again .  OpenVPN works as long as there are no credentials needed .

So, I doubt very seriously that rebooting the router was any consequence .  I think I just finally found a server that was alive and not full ...  I did a few pings; some were dead and I wasn't able to make a connection to some that were alive .

Anyway, I found out that it works .  I don't get any log messages though - I guess I need to enable an option in the log settings somewhere .

Connected from Florida to Washington State ->   I am tired of messing with this for now .  ( I think I need to go on holiday )

You are correct .  All of the attempted connections that I made were OpenVPN servers that did not require usernames or passwords .

I guess most of them were too busy or not working at all .

I was looking around on the internet and found this thread.

I have a premium NordVPN account with all the username and config file, and want to set up a Client to Site OpenVPN.

But it just doesn't work :(

I was using ER605 V1 .
I got a ER605 V2 and it works .  The problem now is that it is extremely slow .
I get 12 Mbps down and up .

When using other OpenVPN clients for Window - I get 300 - 600 down and 235 up .

So, maybe on the next firmware update for the ER605 V1 - it might work .

  @kablammy Hello.

I USE omada oc200 and omada er605. I create an openvpn server for the device. But I can only connect Vpn local. Unable to connect by phone. Can you help me

  @AnhKiet 

Mine was working with NordVPN and I was connecting to a dedicated VPN though .
My dedicated VPN subscription stopped .  I just now tried to connect to another server and I cannot get it working .
I will let you know if I can get it working again .

If you want the phone to use the VPN you should be connecting to a WiFi that is part of your OMADA network .  Such as a TP-Link WiFi EAP or another router that has WiFi which will connect to your ER605 or to your switch .   The WiFi that your phone connect to MUST be behind the ER 605 .

Maybe your phone WiFi is connecting to your cablemodem WiFi ? ? ?
