Description
Technical field
The present invention relates to a kind of online communication technology of broadband cat, the side that especially the LAN causes for gossip of broadband cat are now surfed the Internet
Method.
Background technology
The broadband cat used at present is by telephone wire uplink mostly, i.e. ADSL accesses WAN mouthfuls of modes, passes through WAN causes for gossip
Existing function of surfing the Net.The broadband cat also with multiple LAN ports, can meet multiple users below.But in some occasions, user wishes
Will be LAN mouthfuls one of, WAN mouthfuls are can serve as, is surfed the Internet by way of Ethernet access for other LAN ports, in this way, just very
It is necessary to conversion of the LAN port to WAN port is realized on the cat of broadband.
Thus, the technical issues of being used as WAN mouthfuls of function of surfing the Net by one LAN mouthfuls that solve broadband cat of the invention.
Invention content
The technical issues of present invention need to solve is to provide a kind of method that simple broadband cat LAN causes for gossip are now surfed the Internet.
In order to solve the problem above-mentioned, the present invention devises a kind of method that broadband cat LAN causes for gossip are now surfed the Internet, and feature exists
In including the following steps：
Step 1：Different VLAN tags is respectively configured for each LAN mouthfuls in broadband cat；
Step 2：Wherein some LAN mouthfuls of corresponding software interface is deleted from software bridge；
Step 3：The interface of the default route of broadband cat is set as some LAN mouthfuls of corresponding software interface；
Step 4：Configuration some LAN mouthfuls of corresponding software interface obtains the mode of IP；
Step 5：When uplink message pass through some LAN mouthfuls of corresponding software interface when, establish the link tracking table, with realize by
Downlink message is forwarded to LAN mouthfuls corresponding.
It is further improved as the present invention, which is characterized in that in step 4, some LAN mouthfuls of corresponding software interface obtains
The mode of IP is taken to include static IP configuration mode, DHCP dynamic IPs configuration mode or PPPoE dial modes.
It is further improved as the present invention, nat feature is configured for some LAN mouthfuls of corresponding software interface.
It is further improved as the present invention, the link tracking table includes：Source IP, source port, agreement, destination IP, physics
Port and ageing time.
The present invention also provides a kind of broadband cat, including LAN mouthfuls of at least two, wherein, some LAN mouthfuls is passed through claim
Method setting described in 1-4 has the function of online.
The present invention realizes have network savvy by its LAN mouthfuls on the cat of broadband, is equivalent to and is converted to WAN mouthfuls by its LAN mouthfuls
It uses.In this way, the usage scenario of broadband cat can be increased.
Description of the drawings
Fig. 1 is the structure diagram of broadband of embodiment of the present invention cat；
Fig. 2 is the flow chart of method that broadband cat LAN causes for gossip of the present invention are now surfed the Internet.
Specific embodiment
In order to which relevant technical staff in the field is made to more fully understand technical scheme of the present invention, below in conjunction with figure and implement
The technical solution in embodiment of the present invention is clearly and completely described in mode, it is clear that described embodiment is only
Only it is the embodiment of a part of embodiment of the present invention rather than whole.
The present invention provides a kind of methods that broadband cat LAN causes for gossip are now surfed the Internet, and one LAN mouthfuls on the cat of broadband are converted to
WAN mouthfuls of uses, the function of now networking so as to fulfill LAN causes for gossip.
As shown in Figs. 1-2, the method that the LAN causes for gossip of broadband of embodiment of the present invention cat are now surfed the Internet includes the following steps：
Step 1：Different VLAN tags is respectively configured for each LAN mouthfuls in broadband cat, it is LAN mouthfuls each so as to distinguish.
In the present embodiment, which has the WAN mouths of 4 quantity but is not limited to 4, and different VLAN marks are configured for four LAN mouthfuls
Label, such as：It is the VLAN tags of 2, LAN mouths 13 is 3, LAN mouths 4 that the VLAN tag of LAN mouths 1, which is the VLAN tag of 1, LAN mouths 2,
VLAN tag is 4.When message enters different LAN ports, the VLAN tag of the LAN port will be stamped, if message is from LAN mouthfuls
1 enters, and message can then stamp the label that VLAN is 1.
Step 2：Wherein some LAN mouthfuls of corresponding software interface is deleted from software bridge.In the present embodiment, by LAN
4 corresponding software interfaces of mouth are deleted from software bridge.The broadband cat of this field in default situations, 4 LAN mouthfuls of corresponding softwares
Interface is eth0.1, eth0.2, eth0.3, eth0.4, and software interface eth0.1, eth0.2, eth0.3, eth0.4 are same
In software bridge.
Step 3：In the present embodiment, the interface of the default route of broadband cat is set as 4 corresponding software interface of LAN mouths
eth0.4.In this way, in broadband cat of the present invention, message matching is just walked default route, is corresponded to from LAN mouthfuls less than relevant routing
Software interface eth0.4 go out.
Step 4：The mode that 4 corresponding software interface eth0.4 of LAN mouths obtains IP is configured, in the present embodiment, obtains IP
Mode can be static IP configuration mode or DHCP dynamic IPs configuration mode or PPPoE dial modes.
Step 5：Since the interface of the default route of broadband cat is set as 4 corresponding software interface eth0.4 of LAN mouths, write from memory
Recognize uplink message to go out from eth0.4.When uplink message pass through LAN 4 corresponding software interface eth0.4 of mouth when, establish the link with
Track table, link tracking table with realize downlink message is forwarded to it is LAN mouthfuls corresponding.The link tracking table includes：Source IP, source
Mouth, agreement, destination IP, physical port and ageing time.In the present embodiment, physical port be LAN mouths 1, LAN mouths 2 and LAN mouthfuls
3。
Due to the IP address that IP address is typically all public network being obtained, in order to which LAN mouths 4 is allowed to be able to access that internet, then increase
Add the nat feature of eth0.4.NAT is：NetworkAddress Translation, network address translation.
The LAN mouths 4 of broadband cat of the present invention connect upper internet by cable, you can access internet, realize networking
Function.When uplink message passes through LAN 4 corresponding software interface eth0.4 of mouth, the source IP address of message is replaced by eth0.4
IP address, while establish the link tracking table, for recording transitional information, so that broadband cat can search link tracking table, place
Reason returns to the message (i.e. downlink message) of eth0.4 from internet, and the source IP address of downlink message is converted to LAN port
IP address is forwarded to corresponding LAN port, such as LAN mouths 1, LAN mouths 2 or LAN mouths 3.
The present invention realizes have network savvy by its LAN mouthfuls on the cat of broadband, is equivalent to and is converted to WAN mouthfuls by its LAN mouthfuls
It is using.In this way, the usage scenario of broadband cat can be increased.
Only express one embodiment of the present invention above, description is more specific and in detail, but can not therefore and
It is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that it for those of ordinary skill in the art, is not taking off
Under the premise of present inventive concept, various modifications and improvements can be made, these belong to protection scope of the present invention.Cause
This, the protection domain of patent of the present invention should be determined by the appended claims.
