I have a linux box with two network cards

router 10.152.100.126

eth0 10.152.100.0/24 IP 10.152.100.101

eth1 10.200.100.0/24 IP 10.200.100.129

Eth0 connects to router;

I need to get pcs connected to each LAN to get the appropriate subnet addresses. For example, pc1 on eth1 gets 10.200.100.5 and pc1 on eth0 network to get 10.152.100.5.

Problem is, I keep getting '10.200.100.0/24 no free leases' for the network on eth1. Eth0 is fine though. If I use the share-network inside clause, pc's on both sides of the network get the 10.152.100.0/24

I have a copy of the DHCP.conf file, if anyone can point to the mistake I would greatly appreciate it as this is driving me insane.

ddns-update-style none;
ignore client-updates;
authoritative;
allow booting;
allow bootp;
lease-file-name "/var/lib/dhcpd.leases";

subnet 10.152.100.0 netmask 255.255.255.0 {
filename "pxelinux.0";
range 10.152.100.5 10.152.100.100;
option subnet-mask 255.255.255.0;
option broadcast-address 10.152.100.255;
default-lease-time 3600;
max-lease-time 86400;
next-server 10.152.100.101;
}

subnet 10.200.100.0 netmask 255.255.255.0 {
filename "pxelinux.0";
range 10.200.100.5 10.200.100.100;
default-lease-time 3600;
max-lease-time 86400;
option ip-forwarding off;
option broadcast-address 10.200.100.255;
option subnet-mask 255.255.255.0;
next-server 10.200.100.129;
}

GROUP NETWORK1 {
option routers 10.152.100.126;

option domain-name-servers 192.231.203.3;

host PC01 { hardware ethernet 00:23:AE:06:5D:99; fixed-address 10.152.100.5; }

GROUP NETWORK2 {
option domain-name-servers 192.231.203.3;
host AP01 { hardware ethernet 00:21:5d:da:6d:b4; fixed-address 10.200.100.5; }
}

The subnet sections should be sufficient to get the proper IP leases out the correct interface.

I'm not familiar with the GROUP sections, but it appears that GROUP NETWORK1 might be missing a closing '}'

One more thing... What is the DHCP server's eth1 connected to? A separate broadcast domain, I hope.

Eth1, and the clients for the 10.200.100.0/24 network, should be connected to a separate vlan/broadcast domain than what eth0 is connected to.

hey guys thanks for your input. Yes thanks eth1 and eth0 are seperate domain.

I got this working after all. Just a bit of tinkering was all.

can you post what tinkering made it work so the next that that googles this problem will find the answer? thanks!

The code as posted above is correct. I just checked.
