1 Subnet not getting IP

[Chris Arnold]

I have 2 subnets that are on a shared wire. The 124 subnet is getting IP's fine but the 123 subnet is not. It is getting 124 ip addresses. Here is the dhcp conf file:
authoritative;
option domain-name "domain.tld";
option domain-name-servers 192.168.123.2;
option ntp-servers 192.168.123.2;
ddns-update-style interim;
default-lease-time 14400;
max-lease-time 172800;
Class "123 DHCP Clients" {
         match hardware;
       }
       subclass "123 DHCP Clients" 1:00:0B:DB:C8:F1:71;

Shared-network EH {
       subnet 192.168.123.0 netmask 255.255.255.0 {
         option routers 192.168.123.1;
         pool {
           allow members of "123 DHCP Clients";
	   range 192.168.123.20 192.168.123.250;
         }
       }
       subnet 192.168.124.0 netmask 255.255.255.0 {
         option routers 192.168.124.2;
         pool {
           deny members of "123 DHCP Clients";
	   range 192.168.124.20 192.168.124.253;
         }
       }
}

And here is the entry of what is plugged into the 123 subnet:

Jul  8 21:11:14 mail dhcpd: DHCPDISCOVER from 00:1e:8c:36:08:fb (forgiven) via eth1
Jul  8 21:11:15 mail dhcpd: DHCPOFFER on 192.168.124.251 to 00:1e:8c:36:08:fb (forgiven) via eth1
Jul  8 21:11:15 mail dhcpd: Unable to add forward map from forgiven.electrichendrix.com to 192.168.124.251: timed out
Jul  8 21:11:15 mail dhcpd: DHCPREQUEST for 192.168.124.251 (192.168.124.3) from 00:1e:8c:36:08:fb (forgiven) via eth1
Jul  8 21:11:15 mail dhcpd: DHCPACK on 192.168.124.251 to 00:1e:8c:36:08:fb (forgiven) via eth1

I thought this was working only to find out it is not. What am i doing wrong?
