ok, i found the problem
https://bugzilla.redhat.com/show_bug.cgi?id=512206
so add
net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0
to /etc/sysctl.conf
correct the problem.
I don't know if it's related to redhat kernel, but i didn't have see this problem before.
Maybe it can be add by default to proxmox installer?

Hi,
This morning I see a lot of nf_conntrack error in /var/log/messages.
Is it related to redhat kernel ?
How can I disabled it ?
