What are you trying to set it at? I would just lower the 253 value, so I

Yeah, but even though the router has customizable values for this
range, and issues a warning when i try to change them, it still
doesn't change them when I click "yes" on the warning. It is
pre-configured to 10.0.0.2-10.0.0.253
I could of course use 10.0.0.254 for my static ip, but my room mate
also wants a static address.
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, a netmask of 255.255.254.0 should give you 10.0.0.1 to 10.0.1.254
10.0.1.1 is within range, it should work.
Well problem is, a netmask of 255.255.255.0 means only the last octet
can be used for hosts. Your DHCP server is already assigning addresses
from this space.
Well, I changed it to 255.255.254.0 (0xfffffe00) but kept the dhcp
range as it was.
The DHCP range you are assigning is a subset of what you allowed with
the netmask, thus it is valid.
Yes. As long as the clients have a valid DNS to ask, and a valid gateway
to send their packets, everything will work properly. If you come to
think about it, you are already doing this on the system with the static
So as long as I make my own DHCP server act the same way as the
router one, I should be fine? NAT and all will work?
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".
Ah, yes completely forgot the speedtouch has a telnet interface as well.
I messed with it a few times myself, mostly for fun ;)
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,
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!
I have only done PXE with Windows servers, and it has been quite some
time - cannot remember the details.
I certainly would not advise you to use the router for this - even if it
is possible it has several drawbacks.
- You will, sooner or later, change the router and your new one may not
have the capability
- You will spend a probably unreasonable amount of time trying to make
it work - and it may not even succeed
- Learning how to perform this on FreeBSD will help you apply it in many
I would definitely go the isc-dhcp route.
