The above-mentioned purpose of the embodiment of the present invention, feature and advantage can become apparent from understandable, the most right
In the embodiment of the present invention, technical scheme is described in further detail.
Seeing Fig. 1, for an embodiment flow chart of virtual unit tactics configuring method of the present invention, this is real
Executing example to be described from network equipment side, this network equipment is provided with multiple virtual unit, the method can
To comprise the following steps:
Step 101, for each virtual unit, distribute IP address resource.
In the present embodiment, network device management person can be the most virtual based on IP address resource
Go out multiple virtual unit, corresponding virtual unit will be distributed to by IP address resource, so that this virtual unit
The configurable managed IP address resource distributing to it.Wherein, the IP address of different virtual unit is distributed to
Resource can be the different network segment, and each network segment includes multiple IP address.Such as, by IP address it is
192.168.0.1 the network segment to 192.168.255.255 distributes to virtual unit.In the present embodiment,

In the present embodiment, can include owing to the network equipment realizing the strategy of configuration management based on IP address
Packet filtering strategy and address conversion strategy, therefore when the strategy of virtual unit is configured, if this void
Whether propose standby is that (i.e. whether this virtual unit is assigned IP address money to IP address-based virtual unit
Source), then virtual device management person can be according to distributing to the IP address resource of corresponding virtual unit, to this
The packet filtering strategy of virtual unit and address conversion strategy configure, if this virtual unit is not based on IP
The virtual unit of address, then it represents that this virtual device management person cannot be based on IP address to this virtual unit
Packet filtering strategy and address conversion strategy configure.When configuration address switching strategy, virtual unit
Manager can be to the source NAT switching strategy of this virtual unit, purpose NAT switching strategy, one to one NAT
Switching strategy and multi-to-multi NAT switching strategy configure.
Wherein, packet filtering strategy refers to that the virtual unit message to receiving carries out filtration treatment.Source NAT
Switching strategy refers to that virtual unit is to Intranet when intranet host accesses external network server by virtual unit
The IP address of main frame is changed, and generates public network IP address, so that this virtual unit is according to this public network IP
Address may have access to external network server.Purpose switching strategy refers to when outer net main frame accesses intranet server, empty
Proposing for changing intranet server IP address, generate public network IP address, outer net main frame uses should
Public network IP address just can access the intranet server of correspondence.Before NAT switching strategy refers to conversion one to one
IP address and conversion after IP address use man-to-man relation carry out network address translation.Multi-to-multi
Switching strategy refers to that the IP address before changing and the IP address after conversion use the relation of multi-to-multi to carry out net
Network address is changed.In the above-mentioned switching strategy of NAT one to one and multi-to-multi NAT switching strategy, interior host
The IP address of machine or intranet server is referred to as IP address of internal network, intranet host or intranet server
IP address after conversion, IP address is referred to as public network IP address.

The IP address of intranet host configures, and now virtual unit can carry out source to all messages received
NAT changes；If the part accessed by this virtual unit in whole intranet hosts of external network server is needed
Source to be carried out NAT conversion, then virtual device management person can be to needing to carry out the interior host of source NAT conversion
The IP address of machine configures, and now virtual unit is after receiving message, can first determine whether this message
Source IP address with to need the IP address carrying out the intranet host of source NAT conversion the most identical, if identical,
Then this message is carried out source NAT conversion, otherwise, this message is not carried out source NAT conversion.
It addition, when configuring source NAT switching strategy, if intranet host may have access to institute by this virtual unit
Some external network server, then virtual device management person can not external network server addressable to intranet host
IP address configure, now all messages received can be sent to outside correspondence by virtual unit
Network server；If intranet host may have access to the external network server of part by this virtual unit, the most virtual set
Standby manager can the IP address of external network server addressable to intranet host configure, now, empty
Propose standby after receiving message, can first determine whether that the purpose IP address of this message can be visited with intranet host
The IP address of the external network server asked is the most identical, if identical, then this message is sent to the outer net of correspondence
Server, otherwise, is not sent to the external network server of correspondence by this message.
