FOR SALE: Sophos XG 135 rev 2 eight-port Gigabit router/firewall running OPNsense.

With stock firmware, the device is out of support with the manufacturer. We have extended the device's useful life by installing and configuring 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 the software to its initial state.

The device runs on an Intel Atom C2558 processor (quad-core, 2.4 GHz) with 8 GB of RAM and a 128 GB Transcend SSD (we upgraded both memory and storage from their stock configurations, which were 6 GB and 64 GB, respectively). The processor supports AES-NI crypto and QAT crypto. Networking (eight Gigabit ports) is handled by Intel network interface cards (four i211 and four i354).

The device is implemented in a desktop form factor. The case is all metal and exceptionally rigid.

The device is actively cooled. Under normal operating conditions, the fan is whisper-quiet.

The device is in very good physical condition (please review the photos). A power supply unit with a threaded coupling (no more accidental unplugging!) is included.
