Firewall
This tab is used to configure a firewall that filters out various types of
unwanted traffic on the Routers local network.
SPI Firewall Protection
The SPI (stateful packet inspection) firewall is programmed to recognize
legitimate packets for different types of connections. Only packets
matching a known connection state will be allowed by the firewall; others
will be rejected.
Internet filter services
Filter Anonymous Internet Requests: This feature makes it more
difficult for outside users to work their way into your network.
Filter Multicast: Multicasting allows for multiple transmissions to specific
recipients at the same time. If multicasting is permitted, the Router allows
IP multicast packets to be forwarded to the appropriate computers.
