Hi! I have installed successfully proxmox 2.0 in my server. It has
four network cards: 

vmbr0 -> eth0 physical network card bridge 

vmbr1
-> eth1 physical network card bridge 

vmbr2 -> eth2 physical network
card bridge 

vmbr3 -> eth3 physical network card bridge

if I throw a ping from another network host, and I
do a tcpdump error will look better.

I understand nothing, but the association
Proxmox bad physical network card with bridge. The pings to 10.116.10.26
and 10.116.10.27 will must not operate but no link network card...

I
when installed the VM ClearOS(based in Centos) and I have associated the
follow networks cards via web interface proxmox in the VM:

physical
network card bridge vmbr1 -> eth0 in Centos VM(ClearOS)

physical
network card bridge vmbr2 -> eth1 in Centos VM(ClearOS)

physical
network card bridge vmbr3 -> eth2 in Centos VM(ClearOS)

And all OK but the problem is when I doing ping to host
10.116.10.18, 10.116.10.17 and 10.116.10.16, the all pings have the same
TTL that vmbr1. The TTL host 10.116.10.18, 10.116.10.17 and 10.116.10.16
must be +1. 

I think this a bug problem.... 

Can I help me please??


Sorry for my english, thanks un advanced.
