As ESP is an encapsulation protocol, a value of 4 is also possible, indicating IP in IP. A value of 41 indicates IPv6 encapsulated in IPv4 , e.g. 6to4 . The value 59 (meaning: No Next Header ) is used for dummy packets, which may be inserted in the stream, and which contents should be discarded.
This is carried out over UDP port 500, and commonly uses either a shared password (so-called "pre-shared keys"), public keys, or X.509 certificates on both ends, although other keying methods exist. Establishment of Encapsulating Security Payload (ESP) communication in transport mode. The IP protocol number for ESP is 50 (compare TCP's 6 and ...
Internet Key Exchange (IKE) – User Datagram Protocol (UDP) port 500; Encapsulating Security Payload (ESP) – IP protocol number 50; Authentication Header (AH) – IP protocol number 51; IPsec NAT traversal – UDP port 4500, if and only if NAT traversal is in use; Many routers provide explicit features, often called IPsec Passthrough.
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The (TCP) and the (UDP) only need one for , bidirectional traffic. The (TCP) and the (UDP) only need one for , bidirectional traffic.
NAT traversal: The encapsulation of IKE and ESP in User Datagram Protocol (UDP port 4500) enables these protocols to pass through a device or firewall performing NAT. [14] Stream Control Transmission Protocol (SCTP) support: IKEv2 allows for the SCTP protocol as used in Internet telephony protocol, Voice over IP (VoIP).

* 50 is Encap Security Payload (esp / IPSEC-ESP ) protocol * 51 is IPSEC-AH - Authentication Header protocol Should these be added to this list? Those are not port numbers, those are *protocol* numbers. IPSEC-ESP and IPSEC-AH are IP protocols, just like TCP and UDP. They live at the same layer of the protocol stack.
