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

Sophos XG 135 with stock firmware is in support with the manufacturer until March 2025. Despite this, the manufacturer encourages their customers to upgrade to a newer model. 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 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 on an Intel x553 card and four on an Intel i211 card. There’s also a single SFP port serviced by an Intel i210 card; we confirmed that it works, but we cannot guarantee its compatibility with all SFP cartridges.

A note for pfSense enthusiasts: Intel x553 network interface cards do work with pfSense, but require additional manual configuration, so we do not recommend this device for use with pfSense, unless you are familiar with the manual configuration required.

The device is actively cooled; under the normal conditions, the fan is whisper-quiet. There are two power connectors for redundant power supplies.

The device is in very good physical condition (please review the photos; note that we are running several consecutive listings for identical devices, so the device pictured may or may not be the device you receive, although the photos are representative of the condition of all devices in the series). A power supply unit (alas, only one!) with a threaded coupling (no more accidental unplugging!) is included.
