Description:
Issue
If your FireCluster has an external interface configured with DHCP, active connections that use that external interface will be removed from the connection table when the DHCP server assigns a new IP address, even if the new IP address is exactly the same as the previous IP address.
Workaround/Solution
To avoid this issue, make sure your FireCluster only renews its IP address during non-production hours, or configure the external interface with a static IP address instead of DHCP.
