Dual Router connection settings

First, router settings and computer settings

1 Router setup Ⅰ, see the figure below.

2 router setup Ⅱ, see the following figure:

Change the WAN port address, change the LAN port address, and change the DHCP address range.

Important: The WAN port that the router sets is dynamic IP to obtain an IP address from the first router, change its own IP address and DHCP to another network segment so that it is not on the same network segment as the first router.

Second, the router connection

In this case, a common direct-attached cable is used to connect any one of the LNA ports of the router Ⅰ to the WAN port of the router Ⅱ. See figure below:

Third, the router connection mode description

This way the router Ⅱ do router use, the router can be seen as a computer, so the router Ⅱ and computer ①②③ status is equal. The computer ④⑤⑥⑦ must be Ⅱ this gateway through the router to access it, because the router exists as an isolated device, dividing itself into two halves and a WAN address with ①②③. LAN port address with ④⑤ and so on. Therefore, gateways on computers such as ④⑤ must point to the LAN port address of the router Ⅱ instead of the router Ⅰ. This way is one more machine than the next. This kind of method may let the ④⑤ and so on the speed has slowed down, but the security has greatly improved.

If the router connection fails:

1, unable to set the router

Read the instructions, if not available on the Internet the router official website download. The router is then reset. Connect the router with a single machine, and unplug all remaining network cables. The computer in charge of setting up its own IP address to become automatically acquired, and then see if you can enter the router settings page.

2, unable to access the Internet

If the ①②③ computer is inaccessible, first go to the Router Settings page to see if the WAN port in the running state of the router is connected, that is, whether the Internet is available. If not, check the ADSL account, or switch to a network cable to connect the router Ⅰ wan to ADSL. You can even use the phone line to connect the ADSL directly to see if it is not through.

If it is ④⑤ and other computers can not access. First check that the IP address is Ⅱ the same network segment as the router. and whether the gateway address is correct (the IP address of the router Ⅱ). The DNS address is the IP address of the router Ⅰ, or it can be the IP address of the telecommunications, such as 61.128.128.68. Then check the chart in turn.

Local Network file sharing:

Router Ⅰ must be set up, the following figure, if not set, ④⑤ and other computers can access the local network ①②③, but the reverse is not. Because the computer ① and so on and computer ④⑤ not the same network segment, they can only connect through the router.

There are three situations in the network of authorities:

1, assuming that the computer ① to visit the local network of computer ②, then send information to the router Ⅰ LAN, router Ⅰ after the inspection found to belong to the network segment, through the internal records know the computer ② in which LAN Kou, directly through the LAN port to send to the computer ②.

2, assume that the computer ④ to visit the local network of computer ⑤, ditto. Router Ⅱ sent directly.

3, assuming that the computer ④ to visit the local network of computer ①, router Ⅱ inspection found that does not belong to the network segment, "Not belong to the entire network segment to the WAN port" This iron provisions exist, so the data to the WAN, Wan oral to the router Ⅰ, router Ⅰ check after the discovery of its network segment, through the LAN The mouth is sent directly to the computer ①.

4, assuming that the computer ① to visit the local network of computer ④, after the router Ⅰ check found not belong to the network segment, directly to the WAN, and WAN connections is ADSL, the data out of the news. Therefore, you must let the router Ⅰ know that all access to the computer ④⑤ and other addresses to the router Ⅱ, which is set up in the static route above.

After the router is set up, the computer ① to visit the local network ④, the router Ⅰ check and find the same as the static route setup. By setting, the data for such an address is given to a LAN port connected to it, and the address of the LAN port is the WAN port address of the router Ⅱ. Therefore, the router Ⅰ the data to the router Ⅱ Wan, the router Ⅱ check to find this computer, and then passed to the computer ④.
