FOR SALE: OPNsense nine-port Gigabit router/firewall on Sophos SG 135 rev 3 hardware.

Sophos SG 135 with stock firmware is out of support with the manufacturer effective March 31, 2025. To decouple the device from the manufacturer’s licensing and services, we installed and configured OPNsense, an open-source operating system for networking equipment.

To test the device and make port functions consistent with on-device labeling, we made a few changes to the initial OPNsense configuration. A detailed configuration note will be provided to the buyer. Alternatively, the buyer could simply reset OPNsense to its initial state.

The device runs on an Intel Atom C3558 processor (quad-core, 2.2 GHz) with 6 GB of RAM and a 64 GB SSD. The processor supports AES-NI crypto and QAT crypto.

The device is implemented in a desktop form factor. The case is all metal and very sturdy. There are eight Gigabit Ethernet ports, four Intel x553 and four Intel i211 card. There’s also a single SFP port serviced by an Intel i210 controller; we confirmed that it works, but we cannot guarantee its compatibility with all SFP cartridges.

The device is actively cooled; under the normal conditions, noise level and pitch resemble those of a PC. There are two power connectors for redundant power supplies.

The devices are in fair to good physical condition (please review the photos; we ended up creating a bit of a \"rogue gallery\": for every view, we picked a device that, in our opinion, looked the worst from that particular viewpoint). A power supply unit (alas, only one!) is included.
