The filter purpose is to simulate isolated private VLAN.
|
|
|
982648 |
|
|
|
982648 |
The behavior can be achieved by limiting network traffic
|
|
|
982648 |
to traffic between VM and gateway. Because there is no
|
|
|
982648 |
concept of the PVLAN in the linux bridge.
|
|
|
982648 |
|
|
|
982648 |
The filter also contains parts from clean-traffic
|
|
|
982648 |
to prevent VM from spoofing its IP and MAC address.
|
|
|
982648 |
|
|
|
982648 |
To use this filter the user just needs to set
|
|
|
982648 |
the GATEWAY_MAC variable to gateway MAC address.
