NAT Configuration Check on Egress Interfaces After Reroute

Support for retaining an existing session with Network Address Translation (NAT) rule is available when there is a change in egress interface because of rerouting. If the new egress interface and the previous egress interface are in the same security zone and there is no change in the matched NAT rule or if no rule is applied before and after rerouting, the session is retained with the existing NAT rule. Otherwise, the session expires and new session is created after retransmit or subsequent traffic is received.
