F5 object groups in AFM
- Aug 18, 2025
Hello saddiq_bilal
Address list should support 65k ips, the limit on the firewall address-list / port-lists is due to the mcpd DB size so you might need to adjust it– see https://my.f5.com/manage/s/article/K17883124
However, performance degradation might occur with large numbers of IPs, so I advise to test it. check MCPD and and increase if you have less free space .
To add on, I also found K10978895: Blocking malicious traffic using the IP Intelligence feature in BIG-IP AFM that walks through how to go about blocking IPs if you're interested in taking the next step.
