After receiving the data packet, the REALSERVER unlocks the header of the data packet sent by the DR device, restores the original data packet, and then directly returns the data packet to the client, you do not need to go through DR. It is worth noting that because REALSERVER needs to restore the data packets sent by DR, that is, it must support the IPTUNNEL protocol. The
