Global IP Filters

You can use whitelist and blacklist filter rules to allow or ignore network data capture based on IP address.

Define a whitelist to allow data capture from IP addresses on that list only. Define a blacklist to ignore data capture from IP addressess on the list, and allow data capture from all other IPs.

Whitelist and blacklist IP filters follow these rules:

Whitelist Blacklist Filter results
No No Captures all IPs
No Yes Captures all IPs except blacklist items
Yes No Captures only whitelist IPs
Yes Yes Captures all IPs in whitelist OR IPs not in blacklist

Each filter entry may be a specific IP (v4 or v6) address, or a range of addresses using the following forms:

  • 192.168.2.* (IPv4 octets may use * to indicate wildcard)
  • 10.20.30.0/24 (IPv4 CIDR notation)
  • 2001:0db8:85a3:0042:1000:8a2e:0370:7300/120 (IPv6 CIDR notation)

For more information, see Whitelist or blacklist specific incoming data.
