PFSense router setup and configuration guide
PFSense router setup and configuration guide
Many are discussing PFSense routers. They suggest using it as an alternative to your ISP gateway. This is possible if you have AT&T gateways. You can switch to PFSense for better network management and security.
PFSense is a free router operating system and software compatible with mainly x86 platforms. It’s available for purchase as a dedicated hardware unit from NetGate, the firm behind its main development. You can also obtain customized x86 machines equipped with several Ethernet ports, intended for routing purposes (either PFSense or another solution), or install it on any standard computer or virtual machine within a hypervisor. While effective as a router or firewall, the term "router" here refers to its true function. A device featuring both wireless and LAN switch capabilities is more accurately termed a "SOHO Router" (Small Office / Home Office). Certain NetGate products come with Ethernet switches but lack wireless support—actually, PFSense’s wireless functionality is quite limited, making it best paired with an access point or a router that has been repurposed as an AP by disabling its DHCP service and focusing on LAN ports. By the term "AT&T gateway," I understand you own a comprehensive unit combining DSL modem, router, and wireless capabilities. Such devices often become modems when switched to bridge mode, enabling your own router to operate, though you’ll need to replace the wireless component—either with another SOHO router or a router paired with an AP. If you rely on AT&T fiber service, your gateway likely receives internet via an external ONT using Ethernet or MoCA over Coax. If it uses Ethernet directly, you can probably swap it out entirely (except if TV service is also over fiber, in which case the gateway handles internet through MoCA). If it operates over MoCA, you’ll need to verify whether your provider can convert your ONT to Ethernet.
According to what I've learned, AT&T relies on a problematic gateway that's hard to circumvent for their fiber connections. They don't treat customers like Verizon and Comcast do, which use external ONTs with Ethernet or coax ports, or in the case of Comcast, Ethernet and SFP+ ports.
You'll still require a DSL modem, then connect it into the PFsense device. I'm not an AT&T customer and I don't understand their modem rules.
That would mean it turns into a standard router, but it can't substitute the modem's role.
It's accurate to say PFSense doesn't handle modem tasks since it lacks the necessary hardware. The router you own might function in bridge mode, effectively acting as a modem, or you could consult your ISP for compatible modem-only options available through their site.
