You searched for Untangle and the internet answered with Arista. Nothing is broken and nothing was discontinued — but the rename does change where you download, register and licence the box. Here is the translation, honestly.
If you are following an older tutorial — including videos titled with the Untangle name, like the one on this page — you will hit a confusing moment: the download site, the account portal and current documentation all say Arista Edge Threat Management, while your notes say Untangle. Both are right. Arista Networks acquired Untangle in 2022 and renamed the product; the software line continued. This page is the short, honest map between the two names, focused on the only place it touches a fresh setup: accounts, downloads and licences.
Untangle, the company behind NG Firewall, was acquired by Arista Networks in 2022. The product was renamed Arista Edge Threat Management (ETM) NG Firewall and development continued on the same line — current releases are in the 17.x series. Existing installations kept their rack interface and apps; nobody was asked to reinstall because of a logo. Treat 'Untangle' and 'Arista ETM' the way you treat a person who changed their surname: same entity, new paperwork.
The practical change for a new setup: there is no anonymous direct-download page to bookmark. You create a free ETM Dashboard account, and the portal offers the installer (ISO for hardware, OVA for virtual machines) and becomes the home of your registered appliances. Download only from Arista's own portal — a gateway image is the single worst file on your network to fetch from a mirror site, and renamed-product confusion is exactly what fake download pages exploit.
On versions 16.3 and newer the Setup Wizard itself begins with the account: create an ETM Dashboard account or sign in, and the box is added to it. That link is functional, not decorative — it is how a trial or licence is activated on the appliance and how the appliance appears for central, remote management. Skipping registration leaves you with a routing box whose paid apps cannot be unlocked. There is an offline wizard for boxes with no internet path yet, but the honest default plan is: register during setup.
192.168.2.1, external on DHCPWhich is why an Untangle-era video still teaches a current install faithfully: the clicks moved less than the branding did. A separate guide in this site's Arista set walks the rename and version history in more depth; this page only promises you the setup-relevant truth.
Watch the setup video with the translation above in mind — every Untangle screen it shows is the current Arista ETM product.
▶️ Watch Full VideoNo. Arista Networks acquired Untangle in 2022 and renamed the product Arista Edge Threat Management (ETM) NG Firewall. Development and releases continued on the same line, and existing installations kept working with the same interface and apps.
Through Arista's ETM Dashboard portal, which requires a free account. The portal provides the ISO and OVA installers and is also where your appliances are registered and licensed. Avoid third-party download mirrors — a firewall image must come from the vendor.
No. The rename changed branding, the account portal and where licences are managed — not the installed software. A box installed under the Untangle name updates forward on the same product line; there is no migration or reinstall step caused by the name change.
