CirrusPort Lock down | Impact
Hi All, 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". ...
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.

Kind regards,
