Abstract

A packet forwarding method and an inter-network routing apparatus are provided, wherein the inter-network routing apparatus includes at least two sub-cards used for packet forwarding. The packet forwarding method includes: receiving, by each sub-card of the inter-network routing apparatus, a first packet sent from a transmitting end at the private network side; inquiring, according to the private network IP address and the private network transmission protocol port number carried in the first packet, a corresponding relationship table, which is preset in the sub-card, between the private network address and port and the public network address and port for mapping, and obtaining the public network IP address and the transmission protocol port number for mapping corresponding to the private network IP address and the private network transmission protocol port number; substituting the private network IP address and the private network transmission protocol port number with the public network IP address for mapping and the transmission protocol port number for mapping, and generating a second packet; sending the second packet to the public network side. The present invention improves the packet forwarding speed by disposing the network address translation function into each sub-card.
