Introduction

UDP port 500 is used for IKE traffic from a VPN client to server.

The UDP Port Used for IKE Traffic

The UDP port used for IKE traffic from a VPN Client to Server is 500.

The IKE Protocol

IKE uses UDP port 500. IKE stands for Internet Key Exchange and is the protocol used to set up a security association (SA) in IPsec. Each IKE phase uses different message types to perform different tasks, as described below.

IKE phase 1 authenticates and creates a secure channel between two hosts. This phase has two modes: main mode and aggressive mode. Main mode protects the identities of the hosts, while aggressive mode does not.

IKE phase 2 establishes the IPSec security associations (SAs) that specify the security transforms that will be used for the rest of the connection. There are two ways to do this: quick mode and extended mode. Quick mode establishes new SAs, while extended mode renegotiates existing SAs.

The IKE Packet Format

IKE uses UDP port 500. IKE uses a fixed header format similar to that used by the Internet Security Association and Key Management Protocol (ISAKMP). The IKE header consists of eight fields, each of which is a 32-bit quantity, for a total of 256 bits. cara menambah followers instagram

The IKE Payload

The IKE Payload is used to encapsulate all Internet Key Exchange (IKE) related traffic between a VPN Client and Server. This port is usually UDP 500, but can also be UDP 4500 or UDP 10000 depending on the implementation.
