Router To router: Dual-router connection settings

I. vro settings and computer settings

1) vro settings I, see.

2) vro settings II, see:

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

Key points:The WAN port set by the router is a dynamic IP AddressVroObtain the IP address, change its own IP address and DHCP to another CIDR block so that it is not in the same CIDR block as the first vro.

2. Router connection

Connect any LNA port of vroⅰ I to the WAN port of vroⅱ Ⅱ with a normal direct connection network cable. See:

Iii. Router Connection Methods

In this way, vroⅱ Ⅱ is used as a router and can be regarded as a computer. Therefore, vroⅱ Ⅱ is equal to computer ① ③. Computer ④ can only be accessed through the gateway vroⅱ Ⅱ. Because the router exists as an isolated device, it divides itself into two halves, a wan port address is associated with ① ③. The LAN port address is associated with ④. Therefore, the gateway on the computer such as ④ must point to the LAN port address of vroⅱ Ⅱ, instead of vroⅰ I. This method is more than the previous one. This method may slow down the speed of machines such as ④ 5th, but greatly improves the security.

If the router connection fails:

1. failed to set vro

If you have not read the manual, you can download it from the official website of this vro. Then reset the vro. Connect the vro with a machine and remove all other network cables. The computer that is responsible for setting up its own IP address to be automatically obtained, and then check whether it can enter the vro settings page.

2. unable to access the Internet

If your computer is inaccessible, go to the router settings page to check whether the WAN port in the running status of the router is connected, that is, whether the Internet is connected. If no, check the ADSL account, or change the network cable to connect the WAN port of router I to ADSL. You can even use the telephone line of ADSL to check whether it is accessible.

If it is ④ or another computer, it cannot be accessed. First, check whether the IP address is in the same CIDR block as vroⅱ Ⅱ. And whether the gateway address is the correct IP address of vroⅱ Ⅱ ). Whether the DNS address is the IP address of router I or the IP address of China Telecom, such as 61.128.128.68. Then, check the data in sequence.

Local Network File Sharing:

You must configure vroⅰ I. For example, if you do not set vroⅰ I, you can access the local network (①) (③) on a computer (④), but not on the other hand. Because computer ① and computer ④ are not in the same network segment, they can only be connected through a router.

There are three situations when accessing the authority network:

1. Assume that the computer ① wants to access the local computer ②, then it sends the information to the LAN port of router I. After router I checks, it finds that it belongs to this segment, use an internal record to know which LAN port of computer ② is on, and send it directly to computer ② through that LAN port.

2. Assume that the computer 4 wants to access the local computer 5, the same as above. Vroⅱ Ⅱ directly sends messages.

3. Assume that the computer (④) wants to access the local computer (①) and router II checks and finds that it does not belong to this segment and that the iron "all that does not belong to this segment is thrown to the WAN port" already exists, therefore, the data is sent to the WAN port and the WAN port is transmitted to router I. After router I checks, it finds that the network segment belongs to it and sends it directly to the computer through the LAN port ①.

4. Assume that the computer ① wants to access the computer ④ of the local network. After the router I check, it finds that it does not belong to this network segment and directly drops it to the WAN port, while the WAN port is connected to ADSL, when data is transferred out, there will be no audio. Therefore, vroⅰ I must be aware that all the addresses that access the computer, such as ④ ⑤, must be thrown to vroⅱ Ⅱ, Which is set in the above static routing.

Router settingsAfter vroⅰ I check, the computer ① wants to access the local network ④ and finds it is the same as that set in Static Routing. According to the settings, the data of such an IP address is handed over to a LAN port connected to it. The IP address of this LAN port is the WAN port address of vroⅱ Ⅱ. Therefore, vroⅰ I transmits the data to the WAN port of vroⅱ Ⅱ. After vroⅱ Ⅱ checks the data, it finds the computer and sends the data to vroⅱ ④.
