To configure group mapping on a Palo Alto Networks firewall, follow these steps in order:

Navigate to Device > User Identification > Group Mapping:

This is the initial step where you access the group mapping settings in the web interface.

Add a new group mapping:

After navigating to the group mapping section, the next step is to add a new group mapping configuration.

Enter a unique name to identify the group mapping configuration:

Provide a unique and descriptive name for the new group mapping configuration to easily identify it.

Create an LDAP Server Profile:

This step involves creating an LDAP Server Profile, which defines the connection settings for the LDAP server that will be queried for user and group information.

Select the LDAP Server Profile:

Finally, associate the created LDAP Server Profile with the group mapping configuration. This links the group mapping to the specific LDAP server.

Order in Process:

Navigate to Device > User Identification > Group Mapping

Add a new group mapping.

Enter a unique name to identify the group mapping configuration.

Create an LDAP Server Profile.

Select the LDAP Server Profile.

To match the App-ID adoption task with its order in the process, follow these steps:

Perform a like-for-like (Layer 3/4) migration from the legacy firewall to the Palo Alto Networks NGFW.

This is the initial step to ensure that the Palo Alto Networks NGFW is in place and functioning with the existing security policies.

Capture, retain, and verify that all traffic has been logged for a period of time.

This step involves enabling logging and monitoring traffic to understand the application usage and to ensure that all traffic is being logged.

Clone the legacy rules and add application information to the intended application-based rules.

This step involves creating copies of the existing rules and enhancing them with application-specific information using App-ID.

Verify that no traffic is hitting the legacy rules.

After creating application-based rules, ensure that traffic is now hitting these new rules instead of the legacy rules. This indicates that the transition to App-ID based policies is successful.

Remove the legacy rules.

Once it is confirmed that no traffic is hitting the legacy rules and the new App-ID based rules are effectively managing the traffic, the legacy rules can be safely removed.

Verify that no traffic is hitting the legacy rules.

Remove the legacy rules.

To set up tunnel monitoring on an IPsec VPN tunnel between two offices, the following steps are needed:

A.Create a monitoring profile: This profile defines the criteria for monitoring, such as the IP address to ping and the failure condition.

B.Add an IP address to each tunnel interface: Tunnel monitoring requires an IP address on each tunnel interface to send and receive monitoring pings.

E.Enable tunnel monitoring on each IPsec tunnel: This step activates the monitoring profile on the IPsec tunnel, ensuring that the tunnel is actively monitored and can trigger alerts or failover mechanisms if the tunnel goes down.

These steps ensure that the tunnel is properly monitored, allowing for proactive detection and response to connectivity issues.

To enable access to a public-facing web server for both internal and internet clients using the FQDNpublic.webserver.acme.com, which resolves to the public address99.99.99.2, the necessary combination of NAT policies is:

C.Option C

Policy 11: DMZ to Untrust

Source Zone: DMZ

Destination Zone: Untrust

Destination Address:Web_Server_Public_99.99.99.2

Destination Translation:address: Web_Server_Private_172.16.1.2

Policy 12: Untrust to Untrust

Source Zone: Untrust

Destination Zone: Untrust

Destination Address:Web_Server_Public_99.99.99.2

Destination Translation:address: Web_Server_Private_172.16.1.2

These policies ensure that traffic destined for the public IP address99.99.99.2from both the DMZ and Untrust zones is properly translated to the internal web server's private IP address172.16.1.2.
