Default DHCPD problem - subnet confusion

Hi,

I'm trying to configure an OpenBSD router which will be running DHCPD.
At the moment my problem exists with setting up DHCPD. At boot time I
receive the following error:

Address range 192.168.2.100 to 192.168.2.199 not on net
192.168.2.1/255.255.255.0!

My dhcpd.conf is:


option domain-name "domain.cxm";
option domain-name-servers 192.168.1.1;

subnet 192.168.2.1 netmask 255.255.255.0 {
option routers 192.168.1.1;
range 192.168.2.100 192.168.2.199;
}

My physical setup is:

Netcomm 1300 router/modem with internal IP of 192.168.1.1 - this device
is not routing at present, nor do I want it doing the routing.
red nic = rl1 = static IP 192.168.1.13
green nic = rl0 = static IP 192.168.2.101

My understanding of subnets is not very competent so please be patient.
Any help would be greatly appreciated.

Pf is not currently running either.

The error message isn't accurate (AFAICS) but there is indeed an error:
your routers option is off.

subnet should be 192.168.2.0/255.255.255.0
and router should point to I guess 192.168.2.101

"your routers option is off."

And how do I turn it on? I can't see how it is "off".

Default Re: DHCPD problem - subnet confusion

When I changed my file to read this:

option domain-name "domain.cxm";
option domain-name-servers 192.168.1.1;

subnet 192.168.2.1 netmask 255.255.255.0 {
option routers 192.168.1.1;
range 192.168.2.100 192.168.2.199;
}

I received:
dhcpd: subnet 192.168.2.0/
^
dhcpd:
dhcpd: Configuration file errors encountered -- exiting

Thanks for your help, I'd actually tried that. Any more ideas?

``Off'' as in IT IS WRONG. You're trying to use your neighbour's
frontdoor as your own. Details left as an excercise.

And quit the top-posting, dammit.

So, where have the changes gone? The router is placed in the subnet?

My apologies... I forgot to change the file on the post.

The file now reads:

option domain-name "domain.cxm";
option domain-name-servers 192.168.1.1;

subnet 192.168.2.0/255.255.255.0 netmask 255.255.255.0 {
option routers 192.168.1.101;
range 192.168.2.100 192.168.2.199;
}

The file WAS changed and gave these different errors:

dhcpd: subnet 192.168.2.0/
^
dhcpd:
dhcpd: Configuration file errors encountered -- exiting

The '^' has a tendancy to move around in this Email depending on video
resolution etc. So for reference the ^ is pointing at the space after the /.

Thanks again for your help.

Have you any thoughts as to what JPD is saying by this? He said this if
reference to my router options.

``Off'' as in IT IS WRONG. You're trying to use your neighbour's
frontdoor as your own. Details left as an excercise.

Thanks again,

Sh4d03

Uh, ehm, I didn't notice your _that unfamiliar...so
192.168.2.0/255.255.255.0 is an ip/netmask pair, inserted into dhcpd.conf it
results into:
subnet 192.168.2.0 netmask 255.255.255.0 {
and not double-defined
subnet 192.168.2.0/255.255.255.0 netmask 255.255.255.0 {

next step will probably be to promote a router's address participating that
subnet, best practice would be to call it 192.168.2.1, and - of course - the
router should be there if you ever want to look outside your subnet.

try
option domain-name "domain.cxm";
option domain-name-servers 192.168.1.1;

subnet 192.168.2.0 netmask 255.255.255.0 {
