Redirect traffic of one IP to website URL

So what I’m trying to do is…
At a customer’s house they have an RB951. Their neighbor is stealing their wifi(family member). I know I could easily change the Wifi password, but I’d rather send all the traffic to my website instead, just for fun.
I know the IP address and MAC address of the offending device. My webserver is hosted publicly on GoDaddy, so I can’t just redirect to an IP address. You can’t open my website just with IP.
How can I forward all the offending device’s traffic to my website? I know you need to use the web proxy to do this, and I’ve followed another post on here, but it’s not working. It blocks all traffic, rather than redirecting to my website.
The offending IP is 10.0.0.189.

Short answer: You can’t.

Long answer: It’s possible to do that, but there are some problems. For plain http, you’d need webserver that’s willing to accept requests with any hostname, i.e. you’d need to have full admin access to webserver, it won’t work if you have only some virtual hosting for specific domain. Same for encrypted https, but additionally there’s no way how to present valid certificate to user, there would be security warnings for everything.
