Abstract
A multicast-capable firewall allows firewall security policies to be applied to multicast traffic. The multicast-capable firewall may be integrated within a routing device, thus allowing a single device to provide both routing functionality, including multicast support, as well as firewall services. The routing device provides a user interface by which a user specifies one or more zones to be recognized by the integrated firewall when applying stateful firewall services to multicast packets. The user interface supports a syntax that allows the user to define subsets of the plurality of interfaces associated with the zones, and define a single multicast policy to be applied to multicast sessions associated with a multicast group. The multicast policy identifies common services to be applied pre-replication, and exceptions specifying additional services to be applied post-replication to copies of the multicast packets for the one or more zones.
