It's hard to say exactly if the Array Networks VPN will work on Linux or not, but based on all the information found on the official website, it appears so. They deploy their servers with switches that allow management, and I've also seen on 3rd party websites users that tried to install the VPN on various Linux distributions.
There is also a page with information about the SSL VPNs that can be accessed here: https://www.arraynetworks.com/products-ssl-vpns-features.html
