I see, interesting. The dnsmasq.service does not wait for network-online.target;
This appears to be a duplicate of: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1531184 In addition to the netplan config to ensure it waits for your bridge to come up, you need to delay dnsmasq.service until after the network is online. You can do that with something like this: % mkdir -p /etc/systemd/system/dnsmasq.service.d % echo -e "[Unit]\nAfter=network-online.target\nWants=network-online.target" | sudo tee /etc/systemd/system/dnsmasq.service.d/network-online.conf % reboot After rebooting, you should see that networkd runs, brings up the interfaces, then network-online.target is reached, and lastly dnsmasq is then started. % journalctl -b -o short-monotonic | egrep "(Reboot|networkd|Network is Online|Starting dnsmasq)" [1835835.825873] b1 systemd-networkd[173]: vlan0: IPv6 successfully enabled [1835835.827054] b1 systemd-networkd[173]: vlan0: netdev ready [1835835.837274] b1 systemd-networkd[173]: Enumeration completed [1835835.864747] b1 systemd-networkd[173]: eth1: Lost carrier [1835835.871748] b1 systemd-networkd[173]: eth0: DHCPv4 address 10.8.107.77/24 via 10.8.107.1 [1835835.879184] b1 systemd-networkd[173]: eth1: IPv6 successfully disabled [1835835.908530] b1 systemd-networkd[173]: eth1: Gained carrier [1835835.908903] b1 systemd-networkd[173]: eth1: Configured [1835835.909878] b1 systemd-networkd[173]: vlan0: Gained carrier [1835835.913807] b1 systemd-networkd-wait-online[175]: managing: eth1 [1835836.288648] b1 systemd-networkd[173]: eth0: Gained IPv6LL [1835836.289022] b1 systemd-networkd[173]: eth0: Configured [1835836.290405] b1 systemd-networkd-wait-online[175]: managing: eth1 [1835836.290834] b1 systemd-networkd-wait-online[175]: managing: eth0 [1835836.291077] b1 systemd-networkd-wait-online[175]: ignoring: lo [1835837.760738] b1 systemd-networkd[173]: vlan0: Gained IPv6LL [1835837.761713] b1 systemd-networkd[173]: vlan0: Configured [1835837.762522] b1 systemd-networkd-wait-online[175]: managing: eth1 [1835837.763413] b1 systemd-networkd-wait-online[175]: managing: eth0 [1835837.763705] b1 systemd-networkd-wait-online[175]: ignoring: lo [1835837.764057] b1 systemd-networkd-wait-online[175]: managing: vlan0 [1835838.445945] b1 systemd[1]: Reached target Network is Online.
