We had here same problems like you, but with public IP Addresses only.
Please post your lxc config. Our Workaround was to set a fixed net.hw
address but maybe your problem is different.
Bet regards

Hi,
Thanks for your reply. I am using proxy server to connect to internet.
From the host I am able to ping this proxy server but not from the
container.
Any pointers?
Thanks,

Hello Ibha, ...
To me it seems, that you have a private address for your container,
10.x.x.x, and you connect the network over a bridge interface.
if you are using bridging, you need a separate public-IP for your
container(s).
If you want to connect to the internet over a single public IP (the IP
of your eth0 I assume) you will need to set up IP-mascarading or NAT,
or a reverse proxy, to translate communication between your virtual
LAN, and the internet.
Depending on your needs, you might have also the option to use IPv6,
the above is for classic IPv4.
Greetings, ..

Hi,
I am new to LXC and networking in Ubuntu and need help urgently.
I am able to ping the container from the host and vice versa.
The host can connect to internet but the container cannot.
I pinged gateway from container but that also doesn't work.
However, output of route --n from the container is:
ubuntu@root-local-machine-2:~$ route -n
