Hi,

I am trying to connect my routerOS device to my Linux OpenVPN server. The problem is that when I enable the ovpn-client interface, I lose Internet connectivity (pppoe-client configured on the same routerOS device). And the vpn doesn't work.

If I try to ping anything on Internet after enabling my ovpn-client, I get a "no route to host" error message. But, looking at my routes, the default route is still there...

My configuration on routerOS: My OpenVPN server config on Linux: (always worked fine with the OpenBSD client I am trying to replace with routerOS) Any idea what my problem could be?

You did not enable 'set default route' on the OVPN connection, which is fine.

After establishing the OVPN connection, check IP > Addresses to make sure you do not have the same IP range on different interfaces. All ranges/subnets need to be unique.

Yes, all ranges/subnets need to be unique. And it's the case.

And, looking at the state of my ovpn-interface and looking at the logs of my server, the connection is never successfully established. So my routerOS device doesn't even get it's ip address from the VPN.

We had the same problem with OVPN when using the wrong "Auth" and/or "Cipher". It connected, but could not ping at all.
