The embodiment of the invention discloses a frequency synchronization method which IPsec and related equipment, based on a frequency synchronization method based on IPsec includes: setting up from the gateway device and the main clock clock device where the network for IPsec tunnel encapsulation time synchronization message, time synchronization message carrying the device sends the master clock the time synchronization message time T1, IPsec tunnel by the tunnel identifier uniquely identifies a tunnel identifier to obtain IPsec encryption; message currently received; according to the IPsec encryption message identifier to determine the current tunnel received for the time synchronization message, will receive IPsec encrypted message time T2 record in the IPsec the encrypted messages; using the T1 and T2, using adaptive clock recovery ACR frequency synchronization. The technical proposal provided by the embodiment of the invention effectively solves the frequency synchronization problem from the clock device in the IPsec scene.
