Three types of entries that can be excluded from an external dynamic list (EDL) are IP addresses, domains, and URLs. An EDL is a text file that is hosted on an external web server and contains a list of objects, such as IP addresses, URLs, domains, International Mobile Equipment Identities (IMEIs), or International Mobile Subscriber Identities (IMSIs) that the firewall can import and use in policy rules. You can exclude entries from an EDL to prevent the firewall from enforcing policy on those entries. For example, you can exclude benign domains that applications use for background traffic from Authentication policy1. To exclude entries from an EDL, you need to:
Select the EDL on the firewall and click Manual Exceptions.
Add the entries that you want to exclude in the Manual Exceptions list. The entries must match the type and format of the EDL. For example, if the EDL contains IP addresses, you can only exclude IP addresses.
Click OK to save the changes. The firewall will not enforce policy on the excluded entries.
