[lxc-users] Unable to connect to internet from LXC container

[Gandhi, Ibha (HP Software)]

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 at root-local-machine-2:~$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
