Connecting to a gadget via a local network without physically linking
You have a dedicated gigabit network switch on both networks, but you're unsure if it's a managed type.
The managed switch gives you more flexibility in managing connections and traffic. You can set which ports connect to which devices and control certain data flows. It also lets you manage different types of traffic. You can easily separate your slower internet connection from your faster one, using the appropriate ISP for each.
Turn on your primary network using the Cudy GS108. It seems it's a simple switch rather than a managed device. Having two networks helps accommodate our family setup; the second network can't forward ports and shares an IP across our neighborhood. I use the first for hosting and the second for faster performance. It's more affordable and works well for us. Note: The slower ISP is also more dependable, so I'm staying with them despite higher costs.
That sounds like the most suitable choice, especially with an older PC acting as a PFSense or OPNsense router. It’s important to handle the port forwarding and routing carefully, as it can become quite complex. Be sure to learn about setting up dual WAN properly.
