Exceed limit on Dynamic IP List

L0 Member

On a PA-5050, what is the impact on the firewall if it exceeds the limit?

 

Thanks in advance

Hi @m.palaca ,

 

When parsing the list, the firewall skips entries that do not match the list type, and ignores entries that exceed the maximum number supported for the model. (source: https://docs.paloaltonetworks.com/pan-os/10-0/pan-os-admin/policy/use-an-external-dynamic-list-in-po...

Hi. One of the lists I use has 56899 records, and I have the error "Warning: EDL(IP BlackList XXXXXXXXX) Exceeded maximum number of ips at line 15942 (Module: device)". https://docs.paloaltonetworks.com/pan-os/10-0/pan-os-admin/policy/use-an-external-dynamic-list-in-po...

My PaloAlto of the serious 800 must support 100000 ip's or it doesn't treat it the same as url's.

 

Thnks.,

@fjsantos,

Completely different limits and IPs, Domains, and URLs are not treated the same and are different. You can have a total of 50,000 IP addresses on an 800 series device, but keep in mind that's an aggregate across the device. So outside of the fact that your list exceeds the limit of the platform, if you have other lists they'll also consume part of that 50,000 limit as well.

You can verify the limit on your device by running the CLI command 'show system state filter cfg.general.max-edl-ip*' and you'll see cfg.general.max-edl-ip and the not as well published/documented max-edl-ip-filesize. 

Hi BPry.
Thanks for the clarification. The command show system state filter cfg.general.max-edl-ip shows me as you say, 50000.
What surprised me the most is that the 50000 ip's is the total number of ip's that the device supports, that list 1 plus list 2 plus list "n" do not have to exceed 50000 ip's.

Thank you.
