Problems solved by technology

[0016] 1. ACL rules must be configured additionally, occupying valuable ACL node resources
[0017] 2. The more ACL nodes, the slower the query and the slower the packet forwarding performance
At the same time, it also affects the performance of other applications associated with the ACL
[0018] 3. The configuration is more complicated. If there are similar ACL rules, it is likely to cause conflicts

Embodiment Construction

[0032] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown in , after the packet enters the NAT device, the forwarding entry will be queried to prepare for subsequent forwarding processing. The outbound port for private network users to access the Internet is the port2 port of the device. The outbound port is determined by routing and generally does not change. In actual application, there may be two outbound interfaces, or the outbound interface may change, which can be determined by configuring different outbound interfaces.

[0034] In one embodiment of the present invention, the NAT translation permission flag is configured for the outgoing port in the forwarding table, and at the same time, according to the access requirements, the specific destination address that does not need to be NAT translation processing during access is disabled. For example, in fi...

Abstract

The present invention relates to a method for accessing user of private network into common network. Said method includes the following steps: in the list items necessary for inquiry when the message is processed by network address conversion equipment setting the mark necessary for making network address conversion or not; for message of the described private network user inquiring the described mark to judge that the described message is required for making network address conversion or not, if the described private network user message has need of making network address conversion, said message is converted in network address, then said message can be retransmitted, otherwise, said message can not be converted in network address, and can be directly retransmitted.

Description

technical field [0001] The invention relates to a method for connecting a private network user to a public network, in particular to a device and a method for connecting a private network user to a public network by directly accessing a specific site without performing network address translation. Background technique [0002] With the rapid growth of the number of Internet users and the increasing demand for IP addresses in other related fields, IPv4 address resources are increasingly scarce, so the application of Network Address Translation (NAT) devices in the network is also increasing. The resulting problem is how to solve the networking application problem where a large number of public network addresses and private network addresses coexist in the network. [0003] Such as figure 1 As shown, the message of user PC1 accessing the Internet (Internet) enters through port port1 of the NAT device, and exits through port port2. During this time, an address translation is p...
