container don't use outbound public ip but proxmox public ip

[hzanibel]

Hello,

I have an issue after migration of an openvz container to a newserver. The outbound ip of the container is the server ip and not the public ip assign in proxmox.
No issue in inbound traffic.
The hosting datacenter use failover ip but i don't think that's cause the issue.

Certainely need change some sysctl but all testing failed

Any idea ?

Thanks
