The TZ470W passed its Last Order Day on June 30, 2026, so SonicWall is no longer selling new units. If you already own a TZ470W, security subscriptions, support renewals, and replacement hardware remain available while your device stays in Active Retirement Mode. For new deployments, SonicWall directs customers to the Gen 8 TZ480 series.

Yes. The TZ470W will keep routing and firewalling traffic without an active Advanced Protection Security Suite subscription. What you lose is the live-updated protection: Gateway Anti-Virus, IPS signatures, and Capture ATP sandboxing stop receiving new threat intelligence once the subscription lapses, so the firewall runs but with security services frozen at their last update.

Yes. SonicOS on the TZ470W supports Dynamic DNS providers including No-IP, DynDNS, and ChangeIP at no additional cost from SonicWall. Configuration happens directly in SonicOS, though pricing and account setup for the DDNS provider itself is handled through that provider, not through your firewall license.

Yes. Existing TZ470W owners can still renew Advanced Protection Security Suite (APSS), Essential Protection Security Suite (EPSS), and standard support contracts. Reach out to our team with your serial number or existing SKU, and we'll get you a renewal quote.

SonicWall's official upgrade path for TZ470W customers is the Gen 8 TZ480 series through Secure Upgrade Plus, combining the new appliance and a security subscription in a single purchase. If you specifically need built-in Wi-Fi on the new hardware, let our team know. Integrated wireless in the current Gen 8 lineup is available on the TZ380W, so we can confirm whether that or a TZ480 paired with a SonicWave access point is the better fit for your site.
