Thanks for the input.

This is the way we have done it until now. However, this leaves out the
VPN users as they get their IP from the firewall not the DHCP-server.
And it also has a problem with laptops which have two interfaces
(wireless and wired). The interface that comes up last overwrites the
already existing entry (even if windows does not use the wireless
interface later and uses the wired with the higher priority).

Those are the reasons we wanted to switch.
