Abstract

The invention discloses a protecting method and a device for a gateway. The protecting method for the gateway comprises: receiving a data package sent from a source end; judging whether the data package matches a preset condition which is preset before; when the judged data package matches the preset condition, sending the data package to a target end; when the judged data package does not match the preset condition, and discarding the data package. According to the protecting method and the device for the gateway, the problem that the gateway is prone to attack resulting the network paralysis in the prior art is solved, and therefore the effect of the stable and safe network running is achieved.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a gateway protection method and device. Background technique [0002] The IP address of the current gateway device generally needs to be configured according to the physical interface of the gateway device, and the IP addresses of different physical interfaces cannot be the same, and the number of IP addresses of each physical interface generally has a certain limit. The IP address of the physical interface of the gateway device is generally used for network interconnection, routing and forwarding with the uplink and downlink devices. [0003] NAT (Network Address Translation, Network Address Translation) address pool technology is a technology that is widely used at present, and this technology specifically configures a section of IP address range on the gateway. When the gateway device receives an ARP (Address Resolution Protocol, Address Resolution Protocol) request, if the reques...
