It's actually pretty simple. You set OpenVPN up not to push anything 
that you would have the DHCP server serve. If you want the DHCP server 
to serve different info to the VPN clients (ip range, default route...), 
you have to exploit the fact that VPN client MAC addresses begin with 
FF:FF. That, of coarse, only works with bridged TAP interfaces... 
Otherwise, it's not possible.
