Two subnets in DHCP Server

[Stephan Schöffel]

Hi there,

I'm trying to make my dhcp server provide addresses for two subnets. It 
works well for the first, but not on the second.

Here is the dhcpd.conf


#################################
option option-135 code 135 = text;
option option-135 "pxe";
option space PXE;

ddns-update-style none;
max-lease-time 172800;

authoritative;

use-host-decl-names on;
deny unknown-clients;
default-lease-time 14400;
option domain-name "fh-bingen.de";
option domain-name-servers 143.93.65.1, 143.93.79.1;

subnet 143.93.77.0 netmask 255.255.255.0 {
  option routers 143.93.77.254;
  option vendor-class-identifier "PXEClient";
  default-lease-time 14400;
  max-lease-time 172800;

Host MacMini {
        hardware ethernet 00:16:cb:ab:b6:89;
        fixed-address 143.93.77.189;
 }

} ###Ende 143.93.77.0/24

subnet 143.93.79.0 netmask 255.255.255.0 {
  option routers 143.93.79.254;
  option vendor-class-identifier "FB2";
  default-lease-time 14400;
  max-lease-time 172800;

Host HP_P2015dn {
        hardware ethernet 00:1a:4b:2f:00:9c;
        fixed-address 143.93.79.171;
 }

}


But regarding the logs, it doesn't even seem to listen on the second net.

eth0: network 143.93.77/24: no free leases



The server address is 143.93.77.181. Does it have to have another NIC in 
the 143.93.79.0/24 net?

Thanks
Stephan
