What is IPSEC ESP Port Number Explanation about?
The port numbers in an IPSec-ESP session represent the SPI values that are negotiated during IKE phase 2 tunnel establishment. For pass-through IPSec traffic where the firewall is not terminating the tunnel, a generic value of 20033 is used for both source and destination ports since the actual SPI values are encrypted and not visible.
