To Configure Filtering, Click Network > Filtering > Filtering Configuration
Filtering is useful in controlling the amount of traffic exchanged between the wired and wireless networks. By using filtering methods, we can restrict any unauthorized packets from accessing the network. This is used to drop broadcast and multicast packets. Hence filtering can increase the amount of bandwidth available on the network and increase the network security. Filtering is available in bridge mode and routing mode.
Filters are activated only when they are globally enabled on the device.
Filtering Status: Default status is Disabled
• If Layer 2 Multicast is changed to deny, entire Layer 2 multicast (MAC layer) traffic will be dropped.
• If Layer 2 Broadcast is changed to deny, entire Layer 2 Broadcast (IP layer) traffic will be dropped.
• If Layer 3 Multicast is changed to deny, entire Layer 3 multicast (MAC layer) traffic will be dropped.
• If Layer 3 Broadcast is changed to deny, entire Layer 3 Broadcast (IP layer) traffic will be dropped.
L2 Broad Cast
In a Layer 2 network, broadcasting refers to sending traffic to all nodes on a network. Enable will drop the matching traffic.
L2 Multicast
Multicast is communication between a single sender and multiple receivers on a network. Enable will drop the matching traffic.
L3 Broadcast
A layer-3 broadcast packet is meant for all hosts on the layer-3 network. When a host needs to resolve the layer-3 broadcast, it uses the layer-2 broadcast address for the frame. Enable will drop the matching traffic.
L3 Multicast
Multicast is a technique for one to many and many to many real-time communications over an IP infrastructure in a network. Enable will drop the matching traffic.
Filtering Type Protocol/IP/MAC/Port
An option to create a custom filtering rule to drop traffic with matching MAC/IP/Port/Protocol.
Filtering Type Protocol/IP/MAC/Port
Standard protocol numbers defined by Internet Assigned Numbers Authority.
Source IP Address
Filter packets based on configured Source IP Address.
Destination IP Address
Filter packets based on configured Destination IP Address
Protocol Type
Filter packets based on protocol type (TCP/UDP)
