My setup is this:
Desktop PC - Ubuntu 18.04 LTS -> Ethernet to Asus RT-AC68U Modem with Merlin installed and NordVPN openvpn client installed -> Ethernet to Asus DSL-AC88U Modem connected to wall socket. Recently, my ISP allocated IP/DNS address began leaking.
I use the Asus router to connect other devices, so for convenience, the router has NordVPN installed to protect all devices. I also have two other VPN services installed in this router, both of which do not leak IP/DNS.
Should I run NordVPN from a terminal or Network manager on Ubuntu desktop, no IP/DNS leaks are detected either with the router VPN client enabled or not enabled.
I have tried all sorts of suggestions gleaned from the web and from advice provided by NordVPN tech team, all to no avail other than trashing my networking a couple of times.
Has anyone, any idea or link to a fix which will work?
