Abstract: A method for message transmission comprises: receiving a forward message sent from an internal network device to an external network; transmitting the forward message after replacing the source address of the forward message with a public network IP address; receiving a reverse message sent from the external network to the internal network device; and transmitting the reverse message after replacing the destination public network IP address of the reverse message, which is sent from the external network to the internal network device, with a private network IP address of the internal network device. With the method, the NAT device can support more users, and thus the number of NAT devices is reduced and synchronization can be achieved between the internal network device and the NAT device when the NAT device aging occurs.

Abstract: The present disclosure provides a method, a terminal, and a gateway for transmitting IPv6 packets in an IPv4 network. An IPv6 terminal obtains an IPv6 address of the terminal, where the IPv6 address comprises an IPv4 address, the IPv4 address is an IPv4 address of a gateway or an IPv4 address designated by the gateway, the gateway is a device connecting an IPv6 network to an IPv4 network, or a device connecting a layer 2 network to an IPv4 network, multiple IPv6 terminals are connected to the gateway, and IPv6 addresses of all the IPv6 terminals connected to the gateway comprise the same IPv4 address; and sends an IPv6 packet to the gateway, where the IPv6 packet comprises the IPv6 address as a source address. In embodiments of the present disclosure, traversal of IPv6 packets through an IPv4 network can be implemented, and IPv4 address resources can be saved.

Abstract: The embodiments of the present invention provide a method, a device, and a system for forwarding a packet. The method includes: receiving an IPv6 packet sent by a gateway, and obtaining a flow label of the IPv6 packet, where the flow label of the IPv6 packet is corresponding to a link identity of customer premise equipment in one-to-one correspondence; decapsulating the IPv6 packet; performing network address translation on a decapsulated packet according to the flow label; and forwarding the decapsulated packet according to a translated network address. When multiple links between the gateway and an AFTR are corresponding to the same tunnel for network address translation, in the case that IP addresses of terminal users are overlapping or are the same, different terminal users can be distinguished, so that a terminal user that sends a packet can receive feedback, thus improving customer satisfaction.
