Hi there, I'm receiving no DHCPOffer back from my DHCPDiscover. However, I can tcpdump the machine running dnsmasq and it is receiving the DHCPOffer packets.
Here's my very very simple dnsmasq.conf # To disable dnsmasq's DNS server functionality. port=0 # To enable dnsmasq's DHCP server functionality. dhcp-range=192.168.1.3,192.168.1.8,255.255.255.240,12h # Set gateway as Router. Following two lines are identical. #dhcp-option=option:router,192.168.0.1 dhcp-option=3,192.168.0.1 # Set DNS server as Router. dhcp-option=6,192.168.0.1 # Logging. log-facility=/var/log/dnsmasq.log # logfile path. log-async log-queries # log queries. log-dhcp # log dhcp related messages. Here's the contents of /var/log/dnsmasq.log after running dhclient on a machine connected to the subnet: Apr 14 18:36:57 dnsmasq: started, version 2.80 DNS disabled Apr 14 18:36:57 dnsmasq: compile time options: IPv6 GNU-getopt DBus i18n IDN DHCP DHCPv6 no-Lua TFTP conntrack ipset auth DNSSEC loop-detect inotify dumpfile Apr 14 18:36:57 dnsmasq-dhcp: DHCP, IP range 192.168.1.3 -- 192.168.1.8, lease time 12h I can see the service running with netstat -anp4: Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name udp 0 0 0.0.0.0:67 0.0.0.0:* 1702/dnsmasq udp 0 0 0.0.0.0:1701 0.0.0.0:* 1607/xl2tpd There are no firewalls setup anywhere on my network for the moment. I have been able to get isc-dhcp-server to successfully allocate DHCP requests just fine however, so I don't think it's anything broken with DHCP in general. I'm running Linux kernel 5.6.2 and using dnsmasq from Debian Bullseye. Hopefully someone can work out my issue! Thank you very much!
