Sometimes, customers reach out to us trying to achieve an SSL VPN connection on their legacy ZyWall USG products. Unfortunately, this is nearly impossible to achieve.
In order to offer SSL VPN on our newer USGs, Zyxel has created the SecuExtender SSL VPN software. This software however is not compatible with the old way of setting up SSL VPNs and can only be used on ZyWall or USG devices of the Newer Generation - if you are wondering, which are the older and newer USG firewalls, have a look at this page: https://www.zyxel.com/us/en/products_services/Licenses-for-Unified-Security-Gateway-ZyWALL-Series-Security-Licenses/legacylicenses
