[Bug]: DNSMasq DHCP failure

[1q23lyc45]

Problem description

The DHCP server for dnsmasq is not working.

What steps will reproduce the bug?

1. Turn off DHCP on the router to prevent other devices from obtaining IP addresses. Set my phone to a static IP to connect to WIFI.
2. apt install root-repo && apt install dnsmasq
3. The configuration file (/sdcard/dnsmasq/dnsmasq.conf) is:

# dnsmasq configuration file

conf-dir=/sdcard/dnsmasq/
dhcp-lease=/sdcard/dnsmasq/dnsmasq.leases
pid-file=/sdcard/dnsmasq/dnsmasq.pid

no-hosts
no-resolv
interface=wlan0
dhcp-authoritative
dhcp-range=192.168.0.100,192.168.0.200,255.255.255.0,48h
dhcp-option=3,192.168.0.1
dhcp-option=6,114.114.114.114,185.222.222.222

4. sudo dnsmasq -d -7 /sdcard/dnsmasq
5. dnsmasq started.
6. Other devices in the same network segment still cannot obtain IP addresses.
7. When I copy this configuration file to another Linux computer and use the same method to enable dnsmasq, other devices can obtain the IP address.

In summary, DNSMasq on Termux cannot utilize DHCP server functionality.

What is the expected behavior?

DHCP is available.
