Hello again @tomp , hope you are doing good ,
can you please assist that why i am unable to ping google.com inside my containers , also cant ping host from container
also cant ping another container with its name like ping dev.lxd
Please can you provide the output of lxc config show <instance> --expanded - this is usually a good start for any post to show what you’re using.
Then also output of ip a and ip r on your host and inside the container.
lxc config show dev-brakuschester --expanded

You have the same subnet configured on eth1 and lxdbr0 10.9.4.0/22, and same address 10.9.6.99/22.
This is not valid configuration. You should ensure that the subnet is different on each interface for routing to function correctly.
