Dnsmasq : Configure DHCP Server2021/07/23

	Enable integrated DHCP feature in Dnsmasq and Configure DHCP Server.
[1]	Configure Dnsmasq for DHCP service.

[root@dlp ~]#

vi /etc/dnsmasq.conf

# line 158 : add ranges of IP address to lease and term of lease

dhcp-range=10.0.0.200,10.0.0.250,12h

# line 332 : add entries for Gateway, NTP, DNS, Subnetmask

dhcp-option=option:router,10.0.0.1
dhcp-option=option:ntp-server,10.0.0.10
dhcp-option=option:dns-server,10.0.0.10
dhcp-option=option:netmask,255.255.255.0

[root@dlp ~]#

systemctl restart dnsmasq

[2]	If Firewalld is running, allow DHCP service. DHCP Server uses [67/UDP].

[root@dlp ~]#

firewall-cmd --add-service=dhcp

success
[root@dlp ~]#

firewall-cmd --runtime-to-permanent

success

[3]	That's OK. Configure DHCP Client on client host and verify it works normally.
