Hi *,
I'm using dnsmasq with a few vlan interfaces and each interface is tagged. And running tests with pihole as well as native dnsmasq. An example on how this is setup in both cases (.i.e. pihole as well as native dnsmsaq): ===== # Wired - vlan 210 interface=eth0.210 domain=wired.lan,192.168.210.0/24,local dhcp-range=set:vlan-210,192.168.210.11,192.168.210.99,168h dhcp-option=tag:vlan-210,option:router,192.168.210.241 dhcp-option=tag:vlan-210,option:dns-server,192.168.210.235 dhcp-option=tag:vlan-210,option:ntp-server,192.168.210.235 dhcp-option=tag:vlan-210,option:domain-name,wired.lan ===== The idea behind this is that devices with multiple vlan interfaces have their IP's registered with dhcp and dns. The dhcp part seems to work - all interfaces have the correct IP details. However, the log has numerous wrong-address errors like this (i.e. pihole as well as native dnsmasq): ===== Mar 24 09:02:03 dnsmasq-dhcp[49]: DHCPREQUEST(eth0.210) 192.168.210.201 bc:24:11:87:be:e5 Mar 24 09:02:03 dnsmasq-dhcp[49]: DHCPNAK(eth0.210) 192.168.210.201 bc:24:11:87:be:e5 wrong address Mar 24 09:02:03 dnsmasq-dhcp[49]: DHCPDISCOVER(eth0.210) bc:24:11:87:be:e5 Mar 24 09:02:03 dnsmasq-dhcp[49]: DHCPOFFER(eth0.210) 192.168.210.201 bc:24:11:87:be:e5 Mar 24 09:02:03 dnsmasq-dhcp[49]: DHCPREQUEST(eth0.210) 192.168.210.201 bc:24:11:87:be:e5 Mar 24 09:02:03 dnsmasq-dhcp[49]: DHCPACK(eth0.210) 192.168.210.201 bc:24:11:87:be:e5 osiris ===== Question-1: where are these wrong-address messages coming from? If I look at the dhcp.leases (Pihole) or dnsmasq.leases (native dnsmasq) there is always one entry like this: 1743408124 bc:24:11:87:be:e5 192.168.230.201 osiris * Question-2: why is there only an entry from the last vlan interface of (in this example) osiris? And not one for every vlan interface? Question-3: the same applies for dns regestrations where there is only an entry for the last vlan interface? I have tried to force this dns regestration for all fqdn's for each vlan using the following settings (i.e. pihole as well as native dnsmasq): dhcp-ignore-clid dhcp-fqdn dhcp-client-update expand-hosts domain-needed domain=lan local=/lan/ Does the above ring any bells? Any suggestion? With warm regards - Will
