The Advanced Routing Engine (ARE) is supported on Palo Alto Networks firewalls that utilize the PAN-OS 11.0+ software and have the required hardware architecture. The supported models include PA-3200 Series, PA-5400 Series, PA-800 Series, and PA-400 Series. These models provide enhanced routing capabilities, including BGP, OSPF, and more complex routing policies.

PA-3260 and PA-5410 are part of the PA-3200 and PA-5400 Series, which are known to support ARE.

PA-850 and PA-460 are within the PA-800 and PA-400 Series, which also support ARE

Palo Alto Networks Next-Generation Firewalls (NGFWs) use SSL/TLS profiles to secure connections for services such as GlobalProtect Gateways and GlobalProtect Portals. These profiles are used to manage the SSL/TLS encryption and decryption for secure communication between the firewall and clients (such as VPN clients for GlobalProtect). This helps ensure the confidentiality and integrity of the data during transmission.

In the context of GlobalProtect with certificate-based authentication, certificate profiles are used to ensure proper validation of the certificates. They perform the following functions:

Define trust anchors, which are the root and intermediate Certificate Authorities (CAs) that the firewall trusts to authenticate certificates.

Specify revocation checks, such as CRL (Certificate Revocation List) and OCSP (Online Certificate Status Protocol), to ensure that the certificates being used have not been revoked.

Map certificate attributes, such as the Common Name (CN), which helps in authenticating users and devices based on their certificates.

Server monitoring is the most reliable method for mapping users to IP addresses in PAN-OS. This method allows the firewall to monitor specific servers, such as Microsoft Active Directory (AD) or LDAP servers, to dynamically retrieve and update user-to-IP mappings. It provides a more accurate and up-to-date mapping of users to their associated IP addresses, as it directly queries user databases in real time.

In a hybrid cloud deployment, Ansible is primarily used for automating configurations and policy updates on Palo Alto Networks Next-Generation Firewalls (NGFWs). Through the use of playbooks, Ansible can automate the process of deploying security policies, updating configurations, and managing the firewall's state, which enhances efficiency and consistency across multiple NGFWs in a large or hybrid cloud environment.
