Is there a limit to the number of devices allowed to connect that this rule is trying to enforce?
Either way, if the vr headset doesn't need internet connection you could connect your computer to the internet wirelessly and to your own router via cable for vr.
I don't know much about networking but that page seems to be about someone else setting up a dhcp server without the knowledge of the administrators or the users. In op's case the concerns about mitm attacks don't apply and the other concerns sound like problems that could arise in cases of misconfiguration or if the users aren't aware they're connected to a different network. I also couldn't see anything about it affecting the main network's performance
Why does the dhcp on the router affect the main network? I'd think if it has its own network the main network would only need to deal with the router, as opposed to all the devices connected to the router if it was passthrough?
That's not an ad
