Problems solved by technology

[0004] A firewall only uses one virtual firewall (VFW) to carry these configuration functions, but since a virtual firewall only has one external network interface (Reth1) configured with one public network address EIP, all VPN gateways created by tenants correspond to the external network address are the same (that is, the EIP address configured by Reth1), once the EIP address is unavailable, the VPN gateways created by the VPCs of all tenants will be unavailable

Embodiment Construction

[0023] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] Such as figure 1 Shown, a kind of method that realizes VPN gateway based on cloud computing field, comprises the following steps:

[0026] A. Create a virtual firewall;

[0027] B. Assign the endpoint address IP1 of the local IPSEC, where IPSEC is a protocol function provided for intercommunicating the subnets under the two private clouds;

[0028] C. Configure routing information on the access switch connected to the virtual firewall, so that the subnet traffic under the local virtual private cloud VPC1 can flow to the virtual firewall;

[0029] D. Configure IPSEC rules on the virtual firewall;

[0030] E. End configuration.

[0031] In the step D, the IPSEC rule includes th...

Abstract

The invention provides a method for realizing a VPN gateway based on the field of cloud computing. The method comprises the following steps: A, creating a virtual firewall; B, allocating an endpoint address IP1 of a home terminal IPSEC; C, routing information is configured on an access switch connected with the virtual firewall, so that subnet flow under the VPC1 can flow to the virtual firewall;D, configuring an IPSEC rule on the virtual firewall; E, ending configuration. The invention has the beneficial effects that firewall configuration is effectively reduced, and the firewall fault restart probability is reduced; the isolation of a tenant VPN gateway is provided, different VPCs use different EIP addresses, and the maintainability of operation and maintenance is improved.

Description

technical field [0001] The invention belongs to the technical field of cloud computing, and in particular relates to a method for realizing a VPN gateway based on the cloud computing field. Background technique [0002] If all traffic in the existing data center wants to access the Internet, it needs to go through the firewall for NAT conversion, packet filtering and other processing. Currently, the cloud computing field uses a firewall (FW) as the entity for issuing VPN gateway configuration, and the VPN gateway conversion function is implemented by the firewall. Currently, there is only one set of stacked firewall devices in the data center in the general networking. [0003] Since all traffic and function configurations (including default gateway, EIP, VPN gateway, etc.) are implemented on one firewall, there will be too many device configurations, and the probability of device failure will increase. The device cannot access the external network. Excessive configuration...
