Public bug reported:
Neutron router now supports SNAT when the attribute ``enable_snat`` of the
gateway is set to True.
This will enable all the VMs which has no binding floating IP to access the
public world.
But, generally the DataCenter bandwidths for cloud providers are not free. And
some users may want to buy a higher
SNAT bandwidth for one of their VMs, a CIDR, or a subnet.
So for Neutron, it should support these scenarios:
1. enable/disable SNAT once for all (supported, controlled by ``enable_snat``)
2. enable/disable SNAT for one internal IP (of VM)
3. enable/disable SNAT for a range CIDR of IPs
4. enable/disable SNAT for a subnet
For 2., 3. and 4. scenario should have QoS support.
So I would like to add a new mechanism for Neutron to support these:
1. An new API extension to add specific SNAT type
2. An new L3 agent extension to install SNAT iptables rules.
Ideas?
