URL Filtering is a security profile that allows you to classify web content based on the URL category and reputation of the website. URL Filtering can help you block access to malicious web content, such as phishing, malware, or command and control sites, as well as enforce acceptable use policies for web browsing. URL Filtering uses the PAN-DB cloud service to provide up-to-date information on the URL categories and reputations of millions of websites. You can configure URL Filtering policies to allow, block, alert, continue, or override web requests based on the URL category and reputation, as well as customize the response pages and exceptions for different user groups. References: URL Filtering, Set Up a Basic Security Policy, Updated Certifications for PAN-OS 10.1

The block IP feature can be configured in two Security Profiles: Vulnerability Protection and Anti-spyware. The block IP feature allows the firewall to block traffic from a source IP address for a specified period of time after detecting a threat. This feature can help prevent further attacks from the same source and reduce the load on the firewall1. The block IP feature can be enabled in the following Security Profiles:

Vulnerability Protection: A Vulnerability Protection profile defines the actions that the firewall takes to protect against exploits and vulnerabilities in applications and protocols. You can configure a rule in the Vulnerability Protection profile to block IP connections for a specific threat or a group of threats2.

Anti-spyware: An Anti-spyware profile defines the actions that the firewall takes to protect against spyware and command-and-control (C2) traffic. You can configure a rule in the Anti-spyware profile to block IP addresses for a specific spyware or C2 signature.

Palo Alto Networks firewalls support three types of Ethernet interfaces that can be configured on the firewall: virtual wire, tap, and layer 31. These interface types determine how the firewall processes traffic and applies security policies. Some of the characteristics of these interface types are:

Virtual Wire: A virtual wire interface allows the firewall to transparently pass traffic between two network segments without modifying the packets or affecting the routing. The firewall can still apply security policies and inspect the traffic based on the source and destination zones of the virtual wire2.

Tap: A tap interface allows the firewall to passively monitor traffic from a network switch or router without affecting the traffic flow. The firewall can only receive traffic from a tap interface and cannot send traffic out of it. The firewall can apply security policies and inspect the traffic based on the source and destination zones of the tap interface3.

Layer 3: A layer 3 interface allows the firewall to act as a router and participate in the network routing. The firewall can send and receive traffic from a layer 3 interface and apply security policies and inspect the traffic based on the source and destination IP addresses and zones of the interface4.
