Getting IP/routing conflict error when setting up VPN

[quarantinho]

Hey guys,

let me preface this by saying that I'm somewhat of a noob who's trying to set up a VPN to my dad's house. My dad has sent me a openVPN cfg file which works fine when trying to connect via the Windows OpenVPN Connect programm, however I want all my connections to be routed through the VPN tunnel and thus have tried to set up the configuration right with my router.

My network setup looks like this: Modem -> Router -> PC (via Ethernet) and I'm using the ASUS RT-N66U.

So now here's the problem: When loading the OpenVPN config file in the router's interface and activating the connection, I'm left with this issue: https://imgur.com/rLYZqeF

Apparently there is a "IP/routing conflict" that I seem to be unable to resolve. I've reassigned both the modem as well as my router to different IPs in the LAN, but that didn't solve the problem. What else could be causing this?

First, I do not think you are using OpenVPN Access Server on your router.

Second,

I'm left with this issue:

What issue ?

I think part of the problem is that I don't really understand what the problem itself is (again, I'm pretty much a noob). So I'm having a hard time navigating through the manual as I don't know where to look exactly.

To describe the issue a bit further: I can connect to a VPN via the OpenVPN Client on my windows PC, but I can't make it run "on my router" so to speak - all I'm getting is a "IP/routing conflict" when trying to set up as seen in this picture
