New features
WeOS has in version 4.20.0 been extended with the following new features. See the Release Notes (available at the download page) for detailed information about corrected errors.
• SSL-VPN capacity – the limit for number of SSL-VPN tunnels is now configurable
• Possibility to bind SSL-VPN clients to a specific IP address
• Horseshoe topology – FRNT together with ring coupling can now be used in applications where it is not feasible to close the sub-ring, i.e. find a divergent way back

Horseshoe topology
With Horseshoe topology it is possible to connect one or more open FRNT rings to a super-ring using ring coupling. An open FRNT ring does not have a connection specific connection between the end notes. Only one FRNT ring port is required in each of the end nodes. The picture below gives an example of an application with Horseshoe topology.

Horseshoe topology is further described in the application note “WeOS Horseshoe Topology”.

It is very easy to update WeOS devices using WeConfig.

Simply select the products to be upgraded in the network map and load the new software. A complete backup of the configuration will be performed before the upgrade begins. When you choose to upgrade multiple devices, WeConfig will suggest the best running order. If an update would fail for any reason, WeConfig will automatically retry the procedure. WeConfig manages the entire process, so in larger networks a huge amount of time can be saved as the update process can be set to run overnight.

If you should not be satisfied with the update, it is very simple to roll back to the previous firmware version.
