Linux bridge routing failing on Proxmox3.2/Debian7.0
I am having problems configuring bridged networking on Proxmox3.2/Debian7.0
I have 2 bridges - vmbr0 and vmbr1. I want to attach a gateway/firewall running in a virtual machine between the 2 and use it to connect out to the WAN through vmbr0.
I have removed the IP, mask and gateway from vmbr0 so that the firewall (monowall) can hold those itself.
Virtual machines running under Proxmox will connect to vmbr1 and access the gateway on the inward side on the 10.0.0.0/8 network.
When I switch this config over and reboot the server it does not respond to a ping, or the VPN. What am I doing wrong?

NETWORK_NAMESPACES(7) Linux Programmer's Manual NETWORK_NAMESPACES(7)NAME
network_namespaces - overview of Linux network namespaces
DESCRIPTION
Network namespaces provide isolation of the system resources associated with networking: network devices, IPv4 and IPv6 protocol stacks, IP
routing tables, firewall rules, the /proc/net directory (which is a symbolic link to /proc/PID/net), the /sys/class/net directory, various
files under /proc/sys/net, port numbers (sockets), and so on.
A physical network device can live in exactly one network namespace. When a network namespace is freed (i.e., when the last process in the
namespace terminates), its physical network devices are moved back to the initial network namespace (not to the parent of the process).
A virtual network (veth(4)) device pair provides a pipe-like abstraction that can be used to create tunnels between network namespaces, and
can be used to create a bridge to a physical network device in another namespace. When a namespace is freed, the veth(4) devices that it
contains are destroyed.
Use of network namespaces requires a kernel that is configured with the CONFIG_NET_NS option.
