=== Ingress (NIC) filter ===
The ingress (NIC) filter page, allows setting allow/deny filters for live traffic preprocessing. Filtered out/denied traffic, will NOT become available throughout the dashboard nor the packet ring buffer. Filtered out/denied traffic will be irretrievable for (post) analysis.

For instance if no IP address is denied but a specific MAC address is on the deny list, no traffic for that MAC address will be processed.

NOTE: The ingress (NIC) filter is applied to live traffic only, i.e. the traffic sent to the monitoring interfaces of an Allegro Network Multimeter. When replaying data from the ring buffer, loading a pcap or using the remote traffic capture feature, filtering is not used and/or applied.
=== Important Notes ===
The ingress (NIC) filter is applied to live traffic only, i.e. the traffic sent to the monitoring interfaces of an Allegro Network Multimeter. When replaying data from the ring buffer, loading a pcap or using the remote traffic capture feature, filtering is not used and/or applied.
 
Empty allow lists will discard all traffic so '''no''' traffic will be available for traffic processing.


NOTE: The data recorded to/stored in the Packet Ring buffer, is of course also affected by the Ingress filter. Additional ring buffer capture rules may be configured under "Generic - Packet Ring Buffer", further explained in our wiki here [[Packet ring buffer#Packet%20ring%20buffer%20snapshot%20length%20filter|https://allegro-packets.com/wiki/Packet_ring_buffer#Packet_ring_buffer_snapshot_length_filter]]
