My current internet setup is like this (which is common for most people).
fiber line from ISP <-> ISP fiber modem <-> Personal wifi router <-> switch
This is working fine with no issues. But I need to power two devices. I want to reduce this to a single device.
fiber line from ISP <-> Modem+Firewall PC <-> Switch <-> AP1,AP2...
From my initial research, what I need is an SFP module which can be attached to a PC which supports SFP. OPNsense should be able to handle most SFP modules.
What is the community’s take on this? Is this worth the effort? Can I find a mini-PC which supports SFP? Will it be cost effective?
In terms of electricity cost?
I wouldn’t do it myself.
If you want to know whether it’s going to save money, you want to see how much power it uses — you can use a wattmeter, or look up the maximum amount on the device ratings to get an upper end. Look up how much you’re paying per kWh in electricity. Price the hardware. Put a price on your labor. Then you can get an estimate.
My guess, without having any of those numbers, is that it probably isn’t.
