Problems solved by technology

[0003] With the default routing method, since there is only one egress firewall, when the egress firewall fails, the communication between all hosts in the internal network with this firewall as the default gateway and the external network will be interrupted, and the communication reliability cannot be guaranteed.
[0004] Even if multiple firewalls are used, each firewall cannot form a complementary backup, but only works independently. When one of them fails, other firewalls cannot effectively take over its work, and network interruption may occur

Abstract

The invention uses multi firewalls to construct a highly efficient and stable route link. The invention also provide an apparatus thereof used for providing a virtual gateway address for each firewall; each client is pointed to different virtual gateway so as to balance the traffic on each firewall; when one firewall fails, other firewalls can take over the address of the failure firewall to keepthe network traffic in normal state.

Description

technical field [0001] The invention relates to a multi-firewall load balancing method and device, which belong to the technical field of network communication and information security, and relate to the improvement of routing load balancing and redundant backup technology of firewalls and the improvement of performance. Background technique [0002] Usually, hosts on the internal network are configured with a default gateway, and the next hop is the internal network interface IP address of the egress firewall. In this way, all packets from hosts on the internal network to access the external network will first be sent to the egress firewall, and then the The firewall forwards packets to realize communication between internal hosts and external networks. [0003] With the default routing mode, since there is only one egress firewall, when the egress firewall fails, the communication between all the hosts using this firewall as the default gateway in the internal network and ...
