Dynamic Block List - Limit on number of entries?

[networkadmin]

I've been experimenting with MineMeld and love it - brilliant product 🙂

That said, I'm struggling to get a clear idea what the size limit is of each blocklist.

https://live.paloaltonetworks.com/t5/Learning-Articles/How-are-Dynamic-Block-List-Entries-Counted-on... suggests even a PA200 can handle a list with 50k entries but in the same article it suggests a PA3020 has a limit of just 5k entries.

What is the limit please?  For exampel the Alienvault reputation feed is approximately 16k entries.

Thanks 🙂

Hi,

Please see below:

For PA-200 depends of PAN-OS

Thanks, but that article doesn't make sense unless I'm totally misreading it.

When running PAN-OS 7.0.x on a PA-200, it can have:

• A maximum of 10 External Block Lists
• A maximum of 50000 IPs in all external lists combined. (1 list with 50000 IPs or 10 Lists with 5000 IPs both are supported)

OK so a PA200 can have 1 list with 50,000 IP's that's great but:

Hardware	Maximum Address Entries
PA-200 PA-500	2500
PA-3020	5000
PA-3050 PA-3060 PA-5020	10000
PA-5050	40000
PA-5060 PA-7050	80000

So a PA3020 can only have 5000 entries whilst that table also states that a PA200 can only have 2500 entries.

Some of the reputation feeds out there can be 20k entries and it's hard to believe that a PA200 could use that but a PA3020 could not.

I am with you but cannot confirm as do not have any PA-200 on 7.0.X PAN-OS

Below output from our lab firewall:

BAS-LAB-PA-3050> show system state | match cfg.general.max-address

cfg.general.max-address: 10000
cfg.general.max-address-group: 1000
cfg.general.max-address-per-group: 2500
BAS-LAB-PA-3050>

Cheers

YOu are confusing what the two graphs are actually saying. A PA firewall regardless of version can have 10 external block lists that compose no more than 50000 IPs in total. The graph at the very bottom states how many anddress groups can be on any one device. The EBL that you configure counts as one of these address groups, regardless of how many entries it actually has.
