Firmware Release Notes

Our team of developers is keen to continuously improve our products. Hence, we periodically release firmware updates to not only eliminate errors and raise product quality but also provide new additional features. We base the development of new product features strongly upon our customer's feedback.


Since 2015, Viprinet uses RuggedVPN. RuggedVPN constitutes the next generation of Viprinet firmware and is regularly developed further. From the beginning of 2017, the "Classic" firmware that was used until 2015 is no longer supported. Existing installations should therefore be switched to RuggedVPN in a timely manner in order to profit from all the latest and newest features.

Online update

All our routers provide the option of a simple online update for the "stable" firmware branch in the web interface at [ AdminDesk ] [ Logging & Maintenance ] [ Router Firmware Update ]. The device will automatically check for firmware updates for this specific router model and - if applicable - download and install them. Configuration settings permit that firmware updates will be downloaded without any administrator support when available. However, the installation should always be run with an administrator present.

Offline update

As an alternative to an online update, an offline update is available. From time to time in additional to stable Firmware releases "Cutting edge" firmware releases are made available only as an offline update. To do an offline update, please download the correct firmware image for your product and then use the manual update function inside the router's web interface to upload that image. Both firmware branches, "cutting edge" and "stable", are available from our Update server.

If you need any help or further information concerning firmware updates, please contact our support team.

Viprinet Lifetime Maintenance

Usage of RuggedVPN firmware requires a "Viprinet Lifetime Maintenance" contract being in place. The old Classic firmware is available without having such a maintenance contract. Support for both firmware generations requires a VLM License.

RuggedVPN Stable Firmware Release April 24, 2018 – Version 2017102440/2018041200

On top of our beautiful February stable release, this firmware release is bringing a couple of important bug fixes our partners have requested.

If you wish to upgrade from a Classic firmware, please first update the router to the last stable Classic firmware release (Version 2015081830/2015102900 released on November 27th 2015). Please note that upgrading your firmware from Classic to RuggedVPN requires a Viprinet Lifetime Maintenance license to be in place. For more information, please check It is possible to have Routers and Hubs running on the latest version of the Classic firmware connect to a device running RuggedVPN firmware. However, a compatibility mode will be used in this case, which limits performance and features. It is therefore not recommended to use such a setup in production permanently, but it is OK to have a Classic firmware device talk to a RuggedVPN firmware device while you are upgrading these devices. The Software VPN Client is available both based on Classic Firmware and alternatively based on the RuggedVPN firmware generation. Both versions are still supported, but we recommend migrating to the RuggedVPN one.

The list below lists all new features and bug fixes compared to the previous stable RuggedVPN firmware release (Version 2017102440/2018020600 released on February 13, 2018).

Please note that this stable release does not yet include the new WAN Optimizer feature. A dedicated beta firmware including WAN Optimizer is available through our support team and beta testers’ mailing list.

Bug fixes

  • Having more than 256 routes could cause the dynamic routing engine and router startup to fail.
  • Fixed a bug that could cause routers to reboot once every 24 days.
  • Fixed a problem with dynamic routing that would randomly appear on startups.
  • Fixed WAN modules sometimes getting stuck in “Disconnecting” state, mostly seen with VDSL.
