Choosing hardware for homelab networking & firewalls usually comes down to one trade-off: do you need a dedicated firewall appliance with several wired ports, or are you building around faster-than-gigabit networking? The Sophos SG 125 rev. 2 answers the first need well on paper, but its 1GbE interfaces define its limits.
Quick verdict
At USD 99.99, the Sophos SG 125 rev. 2 is a practical fit for a lab that needs a dedicated firewall/VPN appliance, eight wired network connections, and a compact chassis. It is a weaker match for a setup centered on 10 gigabit links or a rack installation that requires included mounting hardware.
Sophos SG 125 rev.2 1U Hardware Firewall/VPN Appliance w/ 12V DC Adapter
The listed configuration combines an 8-port 1GbE network layout with 4GB of DDR3 RAM and an integrated 64GB SSD intended for logs and quarantine. That gives the appliance a clear role in a home lab: it can sit at the network edge while leaving multiple copper ports available for connected equipment.
The title also identifies firewall and VPN functionality, so it is aimed at buyers looking for more than a basic unmanaged networking device. Its compact desktop/1U form factor may suit a small equipment area, and the included matching 12V DC adapter keeps the package straightforward. The description identifies the unit as tested working, which is useful context when considering a used hardware appliance.
Who it suits
This Sophos appliance makes the most sense for someone planning a firewall-focused lab with gigabit Ethernet, rather than someone shopping specifically for a 10 gigabit network switch. The eight 1GbE ports are a concrete reason to consider it when several wired connections matter, while the 4GB memory and 64GB SSD provide defined internal hardware for the appliance's stated firewall/VPN role.
It can also fit a buyer who prefers a compact unit over a larger chassis. The listed dimensions are approximately 288 × 187 × 44 mm, and the item is identified as 1U in height.
Meaningful trade-offs
The biggest limitation is the network interface specification: all eight ports are listed as 1GbE. If your homelab plan requires 10GbE connectivity, this appliance does not match that requirement based on its listed ports. The external 12V DC power arrangement is another consideration for anyone planning a tightly integrated rack setup.
The appliance is marked used, and rack ears or a rack kit are not included. That does not prevent use as a compact firewall/VPN unit, but it affects how easily it can fit into a rack-oriented build. The 64GB SSD is also a defined capacity rather than a large storage platform, so its role is best understood as the listed logs/quarantine storage rather than general-purpose lab storage.
Bottom line
The Sophos SG 125 rev. 2 is a focused choice for a gigabit homelab firewall or VPN appliance. Its eight 1GbE ports, compact 1U form factor, 4GB RAM, and 64GB SSD give it a clear hardware profile. Choose it when those specifications align with your network; skip it when 10GbE ports or included rack hardware are essential.
