dhcpd gateway settings

[AaronNGray]

I am trying to set up a network and gateway on 192.168.1.x that I am using
for BOOTP'ing servers.

dhcpd.conf
~~~~~~~~~~~
allow booting;
allow bootp;
ddns-update-style interim;
ignore client-updates;
subnet 192.168.1.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.1;
option router-discovery true;
option domain-name-servers 8.8.8.8;
range dynamic-bootp 192.168.1.200 192.168.1.240;
next-server 192.168.0.140;
filename "pxelinux.0";
}
subnet 192.168.0.0 netmask 255.255.255.0 {
}
~~~~~~~~~~

But I cannot seem to get HTTP or other services to work on 192.168.1.x

I have the existing 192.168.0.x network and was wondering how gateway
requests should get from 192.168.1.x to 192.168.0.1 ?

Many thanks in advance,

Aaron

192.168.1.x and 192.168.0.x are different network according to your mask 255.255.255.0 so you are going to need a router to route the packets between the networks. you need to setup a GW for the network.

How do I setup a gateway ?

# --- default gateway
        option routers                  192.168.1.254;
        option subnet-mask              255.255.255.0;
        option broadcast-address        192.168.1.255;

Can you post your network map, please? According your words, you have 2 networks in one broadcast segment, but I'm not shure about this.

Its all on one physical network. I have a Netgear DG834N with the server I am tring to PXEBoot and a Fedora 14 laptop I want as the PXE/BOOTP/DHCP Server plugged in to it.

No routing on the laptop yet which is what I expect I will need.

I want to be able to get HTTP from the internet to do netbooting of different distro's on to the server.

I figure if this is possible it would be a good setup.

If not I have got another Linux Fedora 14 machine with two network cards as standby. But I would really like to get it to work on one physical network, with the laptop as a portable installer.

Then just add this code:

 option subnet-mask 255.255.255.0;
option broadcast-address 192.168.0.255;
option routers 192.168.0.1;
option router-discovery true;
option domain-name-servers 8.8.8.8;
range dynamic-bootp 192.168.0.200 192.168.0.240;
next-server 192.168.0.140;
filename "pxelinux.0"; 
  

to the "subnet 192.168.0.0 netmask 255.255.255.0 {" block, then turn on routing on you server(by "sysctl net.ipv4.conf.all.forwarding=1" command)

BTW, this is very bad idea, to have two networks in one physical segment. If you have more, than 253 computers, use some other network with /16 network mask(10.10.0.0/16, for example).

Surely this will interfere with the existing Netgear router on 192.168.0.x ?
