I have the following problem:
One VLAN: 111
One router with one interface int the 111 VLAN with two IP address:
10.128.43.1, 10.128.42.1 (secondary) On the interface there is an ip
helper-address 10.128.43.121 command!
Two Subnet: 10.128.43.0/24, 10.128.42.0/24
One dhcp server : 10.128.43.121
One clinet: wich would like to give: 10.128.42.80
My config:
cl-test-a:~ # cat /etc/dhcpd.conf
authoritative;
subnet 10.128.42.0 netmask 255.255.255.0
{
# range 10.128.42.20 10.128.42.90;
option domain-name-servers 171.19.9.4;
option domain-name "internal.example.org";
option routers 10.128.42.1;
option broadcast-address 10.128.42.255;
default-lease-time 7200;
max-lease-time 36000;
}
subnet 10.128.43.0 netmask 255.255.255.0
{
# range 10.128.43.20 10.128.43.40;
option domain-name "direkt.osz.kozig.b-m.hu";
option domain-name-servers 171.19.9.4;
option broadcast-address 10.128.43.255;
option routers 10.128.43.1;
option subnet-mask 255.255.255.0;
default-lease-time 7200;
max-lease-time 36000;
}
ddns-update-style none;
log-facility local7;
host bali_nb
{
hardware ethernet 00:c0:9f:29:54:19;
fixed-address 10.128.42.80;
}
And the log:
Nov 16 11:36:46 cl-test-a dhcpd: DHCPDISCOVER from 00:c0:9f:29:54:19 via

If I add a static IP (10.128.42.80) to the client it can ping the dhcp
server.
What maybe the problem?
Thanks,
