That's also for IPsec. Port 4500/udp is used for passing trough NAT devices.
The data packets will not be encapsulated in ESP but in udp packets ofer
More info in:
RFC 3715 IPsec-Network Address Translation (NAT) Compatibility Requirements
RFC 3947 Negotiation of NAT-Traversal in IKE
RFC 3948 UDP Encapsulation of IPsec ESP Packets
