Configure the Firewall to Access an External Dynamic List
You must establish the connection between
the firewall and the source that hosts the external dynamic list
before you can Enforce
Policy on an External Dynamic List.
- (Optional) Customize the service route
that the firewall uses to retrieve external dynamic lists.Select DeviceSetupServicesService Route ConfigurationCustomize and modify the External Dynamic Lists service route.The firewall does not use the External Dynamic Lists service route to retrieve Built-in External Dynamic Lists; content updates modify or update the contents of those lists (active Threat Prevention license required).
- Find an external dynamic list to use with the firewall.
- Create an external dynamic list and host it on a web server. Enter IP addresses, domains, or URLs in a blank text file. Each list entry must be on a separate line. For example:financialtimes.co.inwww.wallaby.au/joeywww.exyang.com/auto-tutorials/How-to-enter-Data-for-Success.aspxSee the Formatting Guidelines for an External Dynamic List to ensure that the firewall does not skip list entries. To prevent commit errors and invalid entries, do not prefix http:// or https:// to any of the entries.
- Use an external dynamic list hosted by another source and verify that it follows the Formatting Guidelines for an External Dynamic List.
- Select ObjectsExternal Dynamic Lists.
- Click Add and enter a descriptive Name for the list.
- (Optional) Select Shared to
share the list with all virtual systems on a device that is enabled
for multiple virtual systems. By default, the object is created
on the virtual system that is currently selected in the Virtual
Systems drop-down.As a best practice, Palo Alto Networks recommends using shared EDLs when multiple virtual systems are used. Using individual EDLs with duplicate entries for each vsys uses more memory, which might over-utilize firewall resources.
- (Panorama only) Select Disable override to ensure that a firewall administrator cannot override settings locally on a firewall that inherits this configuration through a Device Group commit from Panorama.
- Select the list Type (for example, URL
List).Ensure that the list only includes entries for the list type. See Verify whether entries in the external dynamic list were ignored or skipped.If you using a Domain List, you can optionally enable Automatically expand to include subdomains to also include the subdomains of a specified domain. For example, if your domain list includes paloaltonetworks.com, all lower level components of the domain name (e.g., *.paloaltonetworks.com) will also be included as part of the list. Keep in mind, when this setting is enabled, each domain in a given list requires an additional entry, effectively doubling the number of entries that are consumed.
- Enter the Source for the list
you just created on the web server. The source must include the
full path to access the list. For example, https://1.2.3.4/EDL_IP_2015.If you are creating a list of type Predefined IP, select a Palo Alto Networks malicious IP address feed to use as a source.
- If the list source is secured with SSL (i.e. lists with
an HTTPS URL), enable server authentication. Select a Certificate Profile or
create a New Certificate Profile for authenticating
the server that hosts the list. The certificate profile you select
must have root CA (certificate authority) and intermediate CA certificates
that match the certificates installed on the server you are authenticating.Maximize the number of external dynamic lists that you can use to enforce policy. Use the same certificate profile to authenticate external dynamic lists from the same source URL. If you assign different certificate profiles to external dynamic lists from the same source URL, the firewall counts each list as a unique external dynamic list.
- Enable client authentication if the list source has an
HTTPS URL and requires basic HTTP authentication for list access.
- Select Client Authentication.
- Enter a valid Username to access the list.
- Enter the Password and Confirm Password.
- (Not available on Panorama) Click Test
Source URL to verify that the firewall can connect to
the web server.The Test Source URL function is not available when authentication is used for EDL access.
- (Optional) Specify the Check for
updates frequency at which the firewall retrieves the
list. By default, the firewall retrieves the list once every hour
and commits the changes.The interval is relative to the last commit. So, for the five-minute interval, the commit occurs in 5 minutes if the last commit was an hour ago. To retrieve the list immediately, see Retrieve an External Dynamic List from the Web Server.
- Click OK and Commit.
- (Optional) EDLs are shown top to bottom, in
order of evaluation. Use the directional controls at the bottom
of the page to change the list order. This allows you to or order
the lists to make sure the most important EDLs are committed before
capacity limits are reached.You can only change the EDL order when Group By Type is deselected.
- Enforce
Policy on an External Dynamic List.If the server or client authentication fails, the firewall ceases to enforce policy based on the last successfully retrieved external dynamic list. Find External Dynamic Lists That Failed Authentication and view the reasons for authentication failure.
