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.

RuggedVPN

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. 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. The firmware images are available on 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 December 21, 2018 – Version 2018091860/2018111900

This firmware release is bringing a number of product quality improvements and critical stability fixes. We
recommend all customers to update to this release in a timely manner.


In addition to the firmware release from October, this edition is bringing another batch of bug fixes. An updated
firmware image will be available on Amazon AWS as soon as their approval process is finished.


If you wish to upgrade from 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 active. For more
information, please check https://www.viprinet.com/vlm. It is possible to have Routers and Hubs running on the
latest version of Classic firmware connect to a device running RuggedVPN firmware. However, in this case a
compatibility mode will be used, which limits performance and features. It is therefore not recommended to
permanently use such a setup, but it is OK to have a Classic firmware device talk to a RuggedVPN firmware
device while you are upgrading. This REALLY is the final firmware version that still supports connecting old
devices running our Classic firmware generation (2015 and prior) and upgrading from such a firmware release.

The list below lists all new features and bug fixes compared to the previous stable RuggedVPN firmware release
(Version 2018091860/2018100300 released on October 10, 2018).

Bug Fixes

  • In case the local output bandwidth of a WAN Optimizer connection dropped to zero, the WAN Optimizer would
    not notify the remote side to stop sending, therefore filling up the RAM. That's a very rare condition, because
    this can only happen if the receiving side of a TCP user connection would suddenly close the receive window
    forever. There is one case where we have seen this in real life: The "pause download" function of browsers.
  • Removed "HUGE" debug messages that were flooding the logs in some installations, causing lots of
    headaches
  • Fixed an ARP problem on the Hub's WAN Interface. If someone had a terribly broken switch configuration,
    this could cause a Hub's WAN interface to not be reachable for a long time after a reboot or IP change. This
    fix is not an invitation to run out-of-spec ARP cache timeouts on switches
  • If a Multichannel VPN Router 300 runs out of memory, it will reboot. Before rebooting it would write a crash
    log to the flash. It turns out that sometimes the flash write-trough might not have completed by then. This
    could cause the flash to fail. This fix should prevent this to happen. However, keep in mind: On older 300s, the
    flash chip now is over 10 years old and therefore has long passed its typical mean time before failure. We
    recommend to replace your 300 routers.
