Hello,
I am setting up new ISC DHCP Server (version 4.3.5) on Ubuntu 18.04.
This system is configured with single NIC.
Need to configure DHCP server for multiple leases on different Class C
networks.
Googled and tried multiple ways, none of them worked.
*Contents of /etc/dhcpd/dhcpd.conf file *

shared-network companynetwork {
subnet 192.168.40.0 netmask 255.255.255.0{
range 192.168.40.150 192.168.40.160 ;
option domain-name-server 8.8.8.8;
option subnet-mask 255.255.255.0;
option routers 192.168.40.1;
option broadcast-address 192.168.40.255;
default-lease-time 600;
max-lease-time 7200;
}
subnet 10.10.10.0 netmask 255.255.255.0{
range 10.10.10.10 10.10.10.20;
option subnet-mask 255.255.255.0;
option routers 10.10.10.1;
option broadcast-address 10.10.10.255;
default-lease-time 600;
max-lease-time 7200;
}
subnet 192.168.37.0 netmask 255.255.255.0{
range 192.168.37.131 192.168.37.140;
option subnet-mask 255.255.255.0;
option routers 192.168.37.1;

max-lease-time 7200;
}
}
*Contents of/etc/netplan/50-cloud-init.yaml ----- network

addresses:
- 192.168.40.29/24
gateway4: 192.168.40.1

With the above configuration, DHCP addresses get issued from192.168.40.0
pool only, not from other pools.
Any help is greatly appreciated
Thanks in advance
