<div dir="ltr">Hey everyone,<div><br></div><div>I've been trying to configure Ubuntu LXC with 2 ip failover from OVH but i failed :(</div><div>I've been reading many howto's and still nothing. I have found on this list same cool tutorial which has written by Olivier. There is a link: <a href="https://lists.linuxcontainers.org/pipermail/lxc-users/2011-May/001980.html">https://lists.linuxcontainers.org/pipermail/lxc-users/2011-May/001980.html</a></div>
<div><br></div><div>I don't know why i still can't get access to internet from LXC.</div><div><br></div><div>My host ip: <span style="color:rgb(116,116,116);font-family:OpenSans;font-size:14px;line-height:20px;background-color:rgb(245,245,245)">94.23.237.216</span></div>
<div>My ip fail over ip 1: <span style="color:rgb(116,116,116);font-family:OpenSans;font-size:14px;line-height:20px;background-color:rgb(245,245,245)">91.121.239.228</span></div><div><br></div><div>I'll focus on one failover ip. </div>

<div><br></div><div>I think none use public ip/ip failover for LXC ! Is there any why to resolve it ? I would by very very gratefully and i'll subscribed solution on forums when i asked. </div><div><br></div><div>Greetz !</div>
