Working with External Block List (EBL) Formats and Limitations

Hello Gururaj

Below is some additional information -

Dynamic Block Lists

Objects > Dynamic Block Lists

Use the Dynamic Block Lists page to create an address object based on an imported list of IP addresses. The source of the list must be a text file and must be located on a web server. You can set the Repeat option to automatically update the list on the device hourly, daily, weekly, or monthly. After creating a dynamic block list object, you can then use the address object in the source and destination fields for security policies. Each imported list can contain up to 5,000 IP addresses (IPv4 and/or IPv6), IP ranges, or subnets.

The list must contain one IP address, range, or subnet per line, for example:

“192.168.80.150/32” indicates one address, and “192.168.80.0/24” indicates all addresses from 192.168.80.0 through 192.168.80.255.

Example:

“2001:db8:123:1::1” or “2001:db8:123:1::/64”

IP Range:

To specify an address range, select IP Range, and enter a range of addresses. The format is:

ip_addressip_address

where each address can be IPv4 or IPv6.

Example:

“2001:db8:123:1::1 - 2001:db8:123:1::22”

Field

Description

Name

Enter a name to identify the Dynamic Block List (up to 32characters). This name will appear when selecting the source or destination in a policy.

Description

Enter a description for the block list (up to 255 characters).

Source

Enter an HTTP or HTTPS URL path that contains the text file. For example, http://1.1.1.1/myfile.txt. You can also enter a UNC server path.

Repeat

Specify the frequency in which the list should be imported. Youcan choose hourly, daily, weekly, or monthly. At the specified interval, the list will be imported into the configuration. A full commit is not needed for this type of update to occur.

Test Source URL

Test that the source URL or server path is available

Hello, also make sure the URL you specify as source opens up as 'TEXT'

If there are any additional characters than addresses, there will be an issue to read the file.

Also make sure that the URL is reachable by firewall.

Once Dynamic block list is created, then you will be able to choose the same from source or destination address list from security policy.

Hope this helps.

-"You can also enter a UNC server path."


That was a documentation error.


Please refer to:

Dynamic Block Lists and UNC Server Path

It looks like limitation at PA-200 is 2500 lines in EBL or even 2200. Where to learn the exact size for each model?
