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?


Just use the fiber modem, it’s gonna be a huge pain and fight with your ISP to use your own modem likely.
It very strongly depends on which ISP they have. There’s a few that make it easy. There’s a much larger number that can be hacked by a competent pc person (which I’ve done). There’s also a small amount who have worked to make it impossible / hard to do, and don’t have any public info on the process.
My ISP is att fiber, and all I had to do was change the vlan id on the outgoing side and match the ip settings to make it work. I used the guides from https://pon.wiki/ to do it, and the discord is also incredibly helpful.
Of note, this used to be impossible / very difficult so you’ll still find forum posts saying it can’t be done. However, a couple nerds have changed that over the past two years so make sure your info is up to date before deciding it can’t be done for your specific setup.
Shit really? That’s awesome
I checked this route but fiber modem are currently rare. There are only few WiFi 6/7 routers which accepts fiber. My ISP on the other hand is quite friendly. They initially provided me with a fiber modem, which sucked as it was quite old, so I told them to give me a simple modem as I have my own ethernet wifi router. They replaced it the next day.
