D2123IT is a powerful server/router intended for customers that need multiple 10Gbit ports. It's suitable for a 10-Gigabit router or high-performance server applications. 

It's the only passively-cooled 10Gbit hardware we know of.  

 Hardware specification

  • CPU: Intel® Xeon® processor D-2123IT (8 threads, 4 cores) roughly 2x as performant as i7-7500U in multi-threaded applications -
  • 32GB 2666Mhz RAM installed (supports up to 256GB - 4 RAM slots)
  • 1x M.2 SATA port. (comes with 256GB m.2 SSD)
  • 2x 10G SFP+ ports - for optical or copper transceivers (SoC - from CPU)
  • 2x 10GBase-T LAN ports - copper (with Intel X557)
  • 4x 1GbE LAN ports - copper (intel 350-AM4)
  • 1x Dedicated IPMI LAN port (ASPEED AST2500)
  • 2x USB 3.0 
  • 1x VGA port
  • Fanless - passively cooled.

Included in the box

  • 1 x TLSense D2123IT router (as specified above)
  • 1 x Power adapter (plug of your choice)
  • Optical SFP+ Transceiver not included - purchase separately if required. We recommend AOC-E10GSFPSR 

Photos on the left show comparison between the standard size TLSense box vs this one. This product includes only one router.  


  • Full 10Gbit/s routing performance on pfSense 2.5.1 - test results
  • More tests will be performed in the next few days. 

Advantages over competing hardware products

  • Low power consumption in comparison to power - 60W 
  • Low total cost of ownership (no licensing fees, low power consumption)
  • Completely silent. 0 dB - passively cooled. No moving parts.
  • CPU has built-in encryption support (AES-NI), allowing for high VPN throughput.
  • No artificial add-ons required to make your system fully functional
  • No additional charges for extra features - everything is included: unlimited users, unlimited firewall rules, unlimited VPN accounts.
  • No planned obsolescence - future versions of open-source operating systems will continue to work on this hardware.
