In the second image, VW ports mentioned are 1/5 and 1/7. Hence it can not be a part of any other routing. So if any traffic coming as ingress from 1/7, it has to go out via 1/5.

The egress interface for the traffic with ingress interface ethernet1/7, source 192.168.111.3, and destination 10.46.41.113 will be ethernet1/5. This is because the traffic will match the virtual wire with interfaces ethernet1/5 and ethernet1/7, which is configured to allow VLAN-tagged traffic with tags 10 and 201. The traffic will also match the security policy rule that allows traffic from zone Trust to zone Untrust, which are assigned to ethernet1/7 and ethernet1/5 respectively2. Therefore, the traffic will be forwarded to the same interface from which it was received, which is ethernet1/53.

If some sites cannot be decrypted due to technical reasons, such as unsupported ciphers, and blocking them is not an option, then the engineer should add the sites to the SSL Decryption Exclusion list to exempt them from decryption. The SSL Decryption Exclusion list is a predefined list of sites that are not subject to SSL decryption by the firewall. The list includes sites that use certificate pinning, mutual authentication, or unsupported cipher suites. The engineer can also add custom sites to the list if they have a valid business reason or technical limitation for not decrypting them34. Adding the sites to the SSL Decryption Exclusion list will allow the traffic to pass through without being decrypted or blocked by the firewall. References: SSL Decryption Exclusion, Troubleshoot Unsupported Cipher Suites

When planning an upgrade in an environment that includes Panorama, firewalls, and log collectors, it's crucial to follow the recommended sequence to ensure compatibility and minimize disruptions. Palo Alto Networks recommends the following order:

Upgrade Panorama: Start with Panorama because it's the central management platform. Upgrading Panorama first ensures that it's compatible with the new PAN-OS versions that the managed devices (firewalls and log collectors) will be upgraded to. Panorama must be able to support the new versions for it to manage and monitor the devices effectively.

Upgrade the log collectors: Next, upgrade the log collectors. Since log collectors work closely with Panorama to aggregate and store logs from the firewalls, they should be upgraded after Panorama to ensure compatibility. Upgrading the log collectors ensures they can handle the log formats and features introduced in the new PAN-OS version.

Upgrade the firewalls: Finally, upgrade the firewalls. The firewalls are the last components to be upgraded to ensure that they remain compatible with the management and log collection infrastructure. Upgrading the firewalls last minimizes the risk of compatibility issues with Panorama and log collectors.

This sequence ensures that all components are compatible and that the management and logging infrastructure can fully support the firewalls running the latest PAN-OS version.

Quantum-related attack protection requires cryptography resistant to quantum computing, such as post-quantum algorithms. In PAN-OS 11.2, IKEv2 with Hybrid Key Exchange (Option B) combines classical and quantum-resistant algorithms for key exchange, enhancing VPN security. IKEv2 with Post-Quantum Pre-shared Keys (PPK) (Option C) uses pre-shared keys designed to resist quantum attacks, supported in IKEv2 configurations.
