The F5BigCneAddresslist Custom Resource (CR) is useful for defining larger, more complex lists of IP address that can then be referenced by Cloud-Native Network Functions (CNFs) protection and NAT CRs:

  • F5BigNatPolicy - Carrier-grade NAT (CG-NAT) using large-scale NAT (LSN) pools.
  • F5BigFwPolicy - Granulalar packet filtering based on access control list (ACL) policies.
  • F5BigDdosPolicy - Denial of Service (DoS/DDoS) event detection and mitigation.

This document guides you through creating a simple F5BigCneAddresslist.

The CR spec parameters used to configure the Service Proxy TMM static routing table are:

Parameter Description
addresses The IPv4 or IPv6 addresses included in the address list: host 2002::33:22, subnet 2003::/64, or range 22002::33:22-2002::33:50.


Ensure you have:


Use the following steps to install the F5BigCneAddresslist CR:

_images/spk_info.png Tip: Open a second shell to view the CNFs Event Logs while installing.

  1. Copy the example CR into a YAML file:

    apiVersion: "k8s.f5net.com/v1"
    kind: F5BigCneAddresslist
      name: "outbound-nat"
      namespace: "cnf-gateway"
      - "2002::33:22-2002::33:50"
      - "2003::/64"
      - "2004::1"
      - ""
      - ""
      - ""
  2. Install the F5BigCneAddresslist CR:

    kubectl apply -f cnf-address-list.yaml

    In this example, the BIG-IP Controller logs indicate the F5BigCneAddresslist CR was added/updated:

    I0607 12:00:00.12345   1 event.go:282] Event(v1.ObjectReference{Kind:"F5AddressList", 
    F5AddressListProfile cnf-gateway/outbound-nat was added/updated
