f5networks.f5_modules.bigip_firewall_rule – Manage AFM Firewall rules

Note

This plugin is part of the f5networks.f5_modules collection (version 1.9.0).

To install it use: ansible-galaxy collection install f5networks.f5_modules.

To use it in a playbook, specify: f5networks.f5_modules.bigip_firewall_rule.

New in version 1.0.0: of f5networks.f5_modules

Synopsis

  • Manages firewall rules in an AFM (Advanced Firewall Manager) firewall policy. New rules will always be added to the end of the policy. Rules can be re-ordered using the bigip_security_policy module. Rules can also be pre-ordered using the bigip_security_policy module and then later updated using the bigip_firewall_rule module.

Parameters

Parameter Choices/Defaults Comments
action
string
    Choices:
  • accept
  • drop
  • reject
  • accept-decisively
Specifies the action for the firewall rule.
When accept, allows packets with the specified source, destination, and protocol to pass through the firewall. Packets that match the rule and are accepted, traverse the system as if the firewall is not present.
When drop, drops packets with the specified source, destination, and protocol. Dropping a packet is a silent action with no notification to the source or destination systems. Dropping the packet causes the connection to be retried until the retry threshold is reached.
When reject, rejects packets with the specified source, destination, and protocol. When a packet is rejected, the firewall sends a destination unreachable message to the sender.
When accept-decisively, allows packets with the specified source, destination, and protocol to pass through the firewall, and does not require any further processing by any of the further firewalls. Packets that match the rule and are accepted, traverse the system as if the firewall is not present. If the Rule List is applied to a virtual server, management IP, or self IP firewall rule, then Accept Decisively is equivalent to Accept.
When creating a new rule, if this parameter is not provided, the default is reject.
description

Notes

Note

  • For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.

  • Requires BIG-IP software version >= 12.

  • The F5 modules only manipulate the running configuration of the F5 product. To ensure that BIG-IP specific configuration persists to disk, be sure to include at least one task that uses the f5networks.f5_modules.bigip_config module to save the running configuration. Refer to the module’s documentation for the correct usage of the module to save your running configuration.
