F5 AppWorld 2024 session proposal deadline extended to Friday, December 8th!
Hope your are doing great.
I am planning to restrict access on Self IP. Can you please help to understand the impact of port lock down when i change it from allow all to "None".
What things will be impacted like HA or anything and how we can prevent it. We do not have GTM . We have LTMs in HA and some are standalone.
When you lock down the ports you'll shut down everything except for a few exceptions.
The article recommends Default for self IPs used with Network failover or alternately using UDP port 1026.
I'd recommend running the HA services on dedicated VLANs.
