As stated, I’m trying to set up a NAS that plays nice with Spectrum-provided hardware. I’m not the home owner, and the home owner will not budge on using a third-party wifi router that would just act as an access point. I’m trying to set up a small NAS that my friends can access via VPN connection, and I would remote desktop into for administrative needs. I considered Windows Server, but I wouldn’t be able to have it connected to the internet while I set routing and remote access settings, so something that can pick up a DHCP addrese on its own.
Using my powers of total ignorance bolstered by who-gives-a-crap self confidence, I just plugged a second router into the ISP router. That’s the one I put all of my custom settings on. Waiting on other comments to tell me why that’s a bad idea, but it has worked so far
