OPNsense® DEC2770 – 19-inch 1U rack appliance with seven 2.5 GbE ports, two SFP+ and 10 Gbps
Seven 2.5-gigabit ports and two SFP+ at 10 Gbps, 10 Gbps firewall throughput, 1.2 Gbps IPsec, 8 GB DDR4 and 256 GB flash – in a 1U enclosure 242 mm deep.
The DEC2770 is the port-rich version of the DEC2700 series: same AMD Ryzen Embedded processor with four cores and eight threads up to 2.2 GHz on the Netboard A10 Gen3, but seven RJ45 ports instead of three. OPNsense® is preinstalled and one year of the Business Edition is included. Deciso states a total system noise below 40 dB(A). The appliance is developed, manufactured and shipped by Deciso in the Netherlands.
Six reasons for the DEC2770
10 Gbps firewall throughput
830 kpps, up to 8.5 Gbps port to port, 150 µs average latency.
Seven 2.5-gigabit ports
7 × RJ45 at 100/1000/2500 Mbps, freely assignable – seven separate segments without an extra switch.
20 watts in typical operation
Around 40 to 50 euros of electricity per year at common commercial tariffs.
Below 40 dB(A) system noise
Low-noise fan, custom heatsinks and dedicated air ducts according to Deciso.
242 mm mounting depth
214 mm without mounting bracket and handle, so it fits shallow cabinets too.
Made in EU, two-year warranty
Carry-in and return warranty direct from Deciso, including one year of OPNsense® Business Edition.
Typical applications
- Firewall and routing on connections up to 10 gigabit
- Fibre uplink over SFP+ without an additional network card
- Seven separate network segments without an additional switch
- IPsec site-to-site links at 1.2 Gbps
- Rack mounting in shallow cabinets thanks to the 242 mm depth
- Redundant operation with state synchronisation, two units required
Application scenarios are recommendations by inett based on the performance data, not statements by the manufacturer.

Frequently asked questions
Which internet connection can the DEC2752 serve?
Deciso states 10 Gbps firewall throughput at 830 kpps and up to 8.5 Gbps port to port. Over IPsec with AES256GCM16 it is 1.2 Gbps at 178 kpps, with threat protection around 1 Gbps.
How does the DEC2770 differ from the DEC2752?
Only in the number of RJ45 ports: seven 2.5 GbE instead of three. Processor, memory, storage, throughput and enclosure are identical. Typical power consumption is 20 instead of 15 watts and the weight is 2.75 instead of 2.65 kg.
Is OPNsense already installed?
Yes. OPNsense® is preinstalled and one year of the Business Edition is included. That covers the commercial firmware repository, the integrated GeoIP database and the free professional plugins.
How loud is the appliance in a rack?
Deciso states a total system noise below 40 dB(A), measured at a distance of 100 cm, and attributes it to the low-noise fan, custom heatsinks and dedicated air ducts.
Shall we check the sizing together?
We compare line speed, number of users, VPN load and planned services against the performance data. A short message is enough.
More throughput and 25-gigabit ports needed?

One class more throughput?
All measurements refer to TCP traffic unless stated otherwise. Total firewall throughput is calculated from system utilisation and a full-duplex port-to-port performance test. The maximum packet rate was measured with 100-byte packets. IPS performance was measured with ET Open and 1500-byte packets. VPN was measured with AES256GCM16 and SHA512. Concurrent sessions follow from the available memory, where one state occupies 1 KB and 1 GB is reserved for system tasks. Latency is an average over 60 seconds.
