Router/Firewall 1 Ext 2 Int Interfaces VMs on private network

- Brdige : br0 (eth2<->vnet)
- Gateway: 192.168.1.1
- forwarding turned on in kernel
- ifcfg-br0
DEVICE=br0 BOOTPROTO=static ONBOOT=yes IPADDR=192.168.1.9 NETMASK=255.255.255.0 TYPE=Bridge DELAY=0
- ifcfg-eth2
DEVICE=eth2 ONBOOT=yes HWADDR=00:19:66:77:4a:df BRIDGE=br0
- What is going on here is the bridge gives you the network option for br0 in KVM. This gives you VMs on the private address space behind the firewall. The VNET interfaces are autocreated by KVM when new VMs are given ethernet interfaces.
