I managed to change the router ip address to 10.0.0.1/23 and just
keep the default dhcp address space as 10.0.0.2-10.0.0.253. Now I
seem to be able to use 10.0.1.1/24 for my own private use.
(I don't think I really know what I'm doing here, but it works!)

Well, I changed it to 255.255.254.0 (0xfffffe00) but kept the dhcp
range as it was.

Ok, I will look into this.
Also, looking through the telnet interface options (which are far
more than the web interface gives), I see that I can add "dhch
server option templates", "dhcp server option instances" and that I
can assign such an instance to the "dhcp server pool options".
This uses a different config scheme than the isc dhcp server config
files, though. And it seems I need to create a template before I can
create an instance. The template takes a name and an option id as
paramters. The instance, then takes a name, a template, and a value
as mandatory paramters. Also enterprice number, suboption number,
and more.
How does the "filename", "next-server", etc map to option ids? Are
these isomorphic, or do I get this completely wrong?
Does this make any sense to you, or anyone else here? Should I try
to make the router DHCP server serve the right options, or would you
go the isc dhcp route?
Thank you very much for your help so far!
