Concluding notes

If IPSec tunnels are initiated from a specific interface active with the load distribution group, this must be specified in the Advanced Settings for the respective tunnel under the IPSec menu.

The identical WAN interface via which the request was made is again selected automatically in response for forwarding via NAT/PAT. No further configuration steps are required.

IPv6 data traffic is, for example, only routed using the first xDSL-WAN connection, but is also included in the load on the interface.

If both WAN connections support an IPv6 load distribution group, then it must be deactivated on one or the two. In IPv6 there is no NAT mechanism and no proprietary "prefix masking" is implemented. As the selection of the source IP is a matter for the network client behind the be.IP™ it is not otherwise possible to guarantee trouble-free function of services.
