Because ESP packets are unidirectional, NAT devices can't map them like they do with e.g. TCP/UDP packets by using the source and destination ports in those headers. Some NAT devices have a feature, often called something like "IPsec passthrough", that detects IKE traffic from a single host behind the NAT and will forward incoming plain ESP
