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?
You cannot just buy any SFP module and have it work. Most ISPs deploy a “special” (at least compared to normal point to point fiber links) that lets them serve multiple customers out of one port in their office. This is called a Passive Optical Network and requires specialized modules on both ends. There are ways to make a specific SFP work as an ONT and by cloning certain identifiers from the ONT to make the ISP think their box is still there.
This is a lot of effort and from my research, could stop working randomly in some cases.
