Abstract

IKEv2 protocol does not handle dynamic NAT scenarios. Because of this the traffic sent over the IPsec SA will either be dropped or does not reach the peer security gateway. This can be frustrating as user may not understand about the problem. The paper addresses this problem and proposes a method to ensure that IPsec traffic flow seamlessly even in Dynamic NAT scenarios. Keywords—IPsec; IKEv2; NAT; Internet Security
