[Lxc-users] Can not ping outside of local LAN from within a LXC

[Kevin LaTona]

Hi Saurabh,

I have tried that and it has not seemed to matter yet in this setup.

I have been told that the container's /etc/network/interfaces calls should set it, but for whatever reason in this case it is not.

For now at least I am using a "route add default gw 192.168.0.1" in the container's startup script and that is solving the issue.

As even placing the route call in the container's /etc/network/interface stanza has not had an effect yet.


I am curios if people on other OS platforms are having the same issues, as from what I have seen on the web this is not a new problem.

Or if this issue has more to with how Ubuntu 12.04.2 and LXC are currently interacting with each other.

I still don't know and there are still many variables to tie down to know why for sure.

Thanks for your suggestion.

-Kevin
