Layer 2 Filtering
The Layer 2 Filter function of the Router can be
configured to drop a number of packets types as they are
encountered on either interface. This is especially useful
is the Router is configured to operate as a simple bridge.
The packet types that can be filtered are the following:
• ARP
• PPPoE
• IP Multicast
• IPv6 Multicast
• IP Broadcast (blocked by default)
• RARP (blocked by default)
• IPX
• NetBEUI
• Appletalk
• IEEE 802.1Q packets (blocked by default)
• Bridge Management Information
A check mark in the box indicates the packet type will
be passed. Any packet types that are not checked will be
dropped by the Router. Select the packet type you want
to allow to pass and click the OK button.
