To be able to use the browser-based Java SSL Tunnel feature, the web browser must support Java as an NPAPI plugin.
Microsoft Edge does not support NPAPI plugins.
Chrome after version 42 no longer supports or allows the use of NPAPI plugins.
Firefox after version 52 no longer supports or allows the use of NPAPI plugins.
To use DrayTek SSL Tunnel, use the SmartVPN client instead.
The SSL VPN Tunnel feature available on DrayTek SSL VPN routers allows remote teleworkers to connect using either the DrayTek Smart VPN Client or a web browser using the Java SSL Tunnel client.
The Java SSL Tunnel VPN client runs from the router's SSL VPN web interface, it uses a virtual device driver in Windows to operate and requires administrator rights on the machine to run.
