cat /etc/netplan/50-cloud-init.yaml
# This file is generated from information provided by
# the datasource. Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
version: 2
ethernets:
ens3:
dhcp4: true
match:
macaddress: fa:16:3e:79:cf:fc
set-name: ens3
the only work around is to configure statically without DCHP as not to have a
conflicting default GW
ens4:
dhcp4: false
addresses: [10.20.10.18/24]
It should be auto setup without conflicing GW
Please treat it as urgent
