Session Persistence After NAT Configuration Change

If there are any changes in the NAT configuration, then the device retains the existing NAT sessions instead of clearing them. 

NAT session persistence is supported only for source NAT in the following scenarios: 

• Source pool-Change in an address range in a Port Address Translation (PAT) pool. 
• Source rule-Change in match conditions for the address book, application, destination IP address, destination port, source IP address, and destination port fields.
