Embodiment Construction

[0053] figure 1 A schematic diagram of the network architecture used in the embodiment of the present invention, such as figure 1 As shown, the interior such as the virtual local area network 100 corresponding to the server area and the virtual local area network 111 corresponding to the office area interact with the external Internet such as the virtual local area network 11 corresponding to the telecommunications network and the virtual local area network 12 corresponding to the China Unicom network through switches, wherein the switch It mainly includes two main parts, a switching module and a firewall card. The switching module is connected to the external Internet through, for example, the external network interface 1 and the external network interface 2, and is connected to the internal virtual local area network through, for example, the internal network interface 1 and the internal network interface 2. Among them, the above Both the internal network interface and the e...

Abstract

The invention provides a message forwarding method, a switching module, a firewall card and a switch. The method comprises the steps that the switching module receives a data message comprising a target IP address from a first interface connected with the internal virtual local area network; according to the target IP address, whether a second interface for rolling out the data message to be processed is an interface connected with the external internet is determined, and the first interface and the second interface are three-layer interfaces; if yes, according to routing table items of preset hardware, the data message to be processed is redirected to the embedded firewall card for fire preventing and routing processing; the data message processed through fire preventing and routing processing is received and forwarded. Whether the interface for rolling out the data message input from the three-layer internal network interface is the external network interface is determined, if yes, the data message is redirected to the firewall card according to the routing table items of the preset hardware, and therefore the switching module can manage firewall cards uniformly, the configuration is convenient and fast to carry out, and the management is convenient.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a message forwarding method, a switch module, a firewall card and a switch. Background technique [0002] Since the Internet (Internet) protocol is based on the open Transmission Control Protocol / Internet Protocol (Transmission Control Protocol / Internet Protocol, hereinafter referred to as TCP / IP) protocol, the security problems of various enterprise networks and campus networks have become increasingly prominent. The security solution of the switch combined with the firewall can not only solve some network security problems, but also bring greater convenience to users by embedding the firewall card in the core switch on some occasions. The specific performance is: the processing performance of the firewall card is extremely strong and can reach 10G processing The level and firewall cards are embedded in the switch, which makes it very convenient for users to wire and save ...
