Using SSLVPN and IpSec as a Single Connection with automatic fallback to simply enduser handling?

Thanks Ralf, that is the plan, though it's just not part of this release. 

This could be struggling as SSLVPN is independent of the xg-wan interface, means xg is accepting on any WANport ssl-vpn connections.

IPsec is dedicate to one single interface without any option to add additional interfaces (just only one profile can be configured).
That makes WAN connection backup impossible for IPsec.

Without fundamental changes on xg there won't be no way to do this if you run multiple wan interfaces.

The setup of both Connections is possible with the 2.0 Client using different architecture. You're right, there are differences. But having two working connections with SSLVPN and IpSec there should be no problem having an automated failover.

...as long as you are using just a singe WAN interface you are right, but in real live you always will have at least 2 WAN interfaces for backup. If so, it won't work as explained.
