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?


Those two devices are likely very low power arm devices. I wouldn’t be surprised if a mini pc consumes more power than those two devices. If power is your concern you should probably measure how much they’re actually pulling.
Maybe correct? Though my cable modem gobbles down some 15W… Without even doing the Wifi… So, I bet this isn’t a universal truth, as a Mini-PC will comsume less and provide all kinds of extra services, networking, NAS…
