LXC ARP issue

[Sascha72036]

Hello,

i run in my cluster several LXC containers with more than one ipv4 address.
Every lxc container have one ipv4 address in the proxmox "network" configuration.
We add each further in the interfaces file via:

up ip addr add 45.132.89.134/24 dev eth0

My problem is: It seems as if the LXC container does not send any arp requests via the additional ip addresses.
The problem is fixed as soon as we run the following command:

arping -S IP_ADDRESS GATEWAY


But this is only a temporary solution until the arp timeout.

Thanks for your help.
