f5networks.f5_modules.bigip_firewall_rule module – Manage AFM Firewall rules

Note

This module is part of the f5networks.f5_modules collection (version 1.17.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

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

Comments

action

string

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.

Choices:

  • accept

  • drop

  • reject

  • accept-decisively

description

string

The rule description.

destination

Leaving this field blank applies the rule to all addresses and all ports.

You can specify the following destination items. An IPv4 or IPv6 address, an IPv4 or IPv6 address range, geographic location, VLAN, address list, port, port range, port list or address list.

You can specify a mix of different types of items for the source address.

port_list

string

Specifes an existing port list.

This option is only valid when protocol is tcp(6) or udp(17).

port_range

string

This parameter is only relevant when protocol is either icmp(1) or icmpv6(58).

code

string

Specifies the code returned in response to the specified ICMP message type.

You can specify codes, each set appropriate to the associated type, such as No Code (0) (associated with Echo Reply (0)) and Host Unreachable (1) (associated with Destination Unreachable (3)), or you can specify any to indicate the system applies the rule for all codes in response to that specific ICMP message.

You can also specify an arbitrary code.

The ICMP protocol contains definitions for the existing message code and number pairs.

type

string

Specifies the type of ICMP message.

You can specify control messages, such as Echo Reply (0) and Destination Unreachable (3), or you can specify any to indicate the system applies the rule for all ICMP messages.

You can also specify an arbitrary ICMP message.

schedule

string

Specifies a schedule for the firewall rule.

You configure schedules to define days and times when the firewall rule is made active.

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.
