Can you please tell me how many IP addresses can be blocked this way? Are there any limits on the number of addresses/ranges in a file? Unfortunately, I did not find an answer to the question in the known limitations. I would also like to know what will happen if the files with lists duplicate IP addresses. How will SecureXL work with this? And are there any limits on the number of hosts in a policy if you block in the standard way via a blocking rule in the FW policy?</P><P>I will be glad to receive your answers.<BR />Kind regards,<BR />Ruslan</P> Mon, 10 Mar 2025 14:27:17 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Blocking-addresses-using-a-link-with-a-list-of-malicious-IP/m-p/243439#M47297 _karruma_ 2025-03-10T14:27:17Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Blocking-addresses-using-a-link-with-a-list-of-malicious-IP/m-p/243440#M47298 <P>TAC should know the answer.</P> <P>But 77.30 is pretty outdated..</P> <P>Akos</P> Mon, 10 Mar 2025 14:32:36 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Blocking-addresses-using-a-link-with-a-list-of-malicious-IP/m-p/243440#M47298 AkosBakos 2025-03-10T14:32:36Z
