VPN Client configuration for ER605 (though OMADA controller)

  @sonysaini82 

Which kind of the VPN did you set? PPTP/L2TP/OpenVPN?

What exactly is the VPN server?

And you can follow the User Guide:

If you are setting up a VPN you may find it easier to setup / access if you use OPENVPN

OpenVPN has an app that is easier to use for connection to the VPN

how device's are going to connect to client (the one i configure on ER605).

Also I'm guessing you are trying to set the ER605 as a VPN server, rather than a client?  Namely your phone / laptop etc will connect into the ER605?
