Official OPNsense Hardware: DEC2770 in the Rack

If you follow my channel you’ll know I’ve covered a fair bit of OPNsense gear lately, including Deciso’s compact DEC675 and DEC677 desktop units. In today’s video and write-up I go hands-on with the rack-mount DEC2770: we unbox it, run through first boot, and walk step-by-step through upgrading OPNsense Business Edition from 24.4 (Savvy Shark) to 25.4, with snapshots, firmware checks, release notes, and a few tips to keep things bullet-proof.

To help you pick the right appliance, I’ve also included a concise DEC677 vs DEC2770 comparison — CPU, memory, storage, ports and realistic use-cases.
