Dual WAN Router Setup Issues

1 Can't use two WAN ports at the same time, one is a router problem, the other is a setting problem, I prefer that the router has a problem, 2 This has nothing to do with the speed of the bandwidth, 3 Dual WAN routers, I don't think it's special, the key depends on the function and performance of the router.

4. If there is a requirement in this regard, it is recommended to change a router, it is recommended to use the router of Xia Nuo, you can add these two QQ consultation: 393388835 673063559

I don't know if you're an Internet café or a unit, my Internet café is using Xia Nuo's GQF550, 300 machines, it's okay.

1. It is possible that a loop has been generated.

2. It has nothing to do with the rate.

3. I don't know for the time being.

4. Do ISA firewall, it's OK. ISA is currently a more practical office and Internet café firewall.

I'll come back later to replenish and eat now.

2. It has nothing to do with speed.

3. Set it up according to the manual, there is generally nothing special, as long as the two lines can be connected.

4,I don't know if that one has this function.,Yes, if you want to prevent and control**You can choose a high-end one with a strong function in this area.。 The one used by my company is a thriving, 4wan port, which is very easy to use. But there is no such function, only monitoring.

1. Why do you need to have more than one mouth?

There are three main purposes for routers to connect multiple broadbands:

Increased bandwidth: The host can access the Internet through any broadband, which is equivalent to a higher speed bandwidth from the perspective of application.

Redundant backup: If one of the bands fails, you can use the other bands to access the Internet to ensure that the network is uninterrupted.

ISP routing: the so-called "access to Unicom to go to Unicom, access to China Telecom to go to telecommunications", so that the purpose of the visit takes the right path.

2. Can the bandwidth of multiple broadband bands be superimposed?

A: There are two ways to think about it:

1] For the entire LAN, the number of egress bandwidths is large, which is equivalent to the increase of the total bandwidth, which can have a superimposed effect.

2] For a specific host, whether multiple bands can be stacked depends on the application of the host. Let's answer with a column:

The interface router of the network where host A is located pulls two broadbands as follows:

Interface. Note: M here is Mbps, 1byte=8bit, e.g. 512kbps=64kbps.

What is the Internet access bandwidth of intranet host A regardless of the bandwidth occupied by other hosts?

Upload: The maximum upload speed of the host to a server on the Internet is 64 kbps (512 kbps). The reason is that when uploading to the same server, only a certain WAN port can be used. For example, QQ uploads, email attachments, network disk uploads, etc.

In the case of multi-link uploads, the upload speed can be stacked.

Multi-link**: If it is turned on Thunderbolt**, the number of resources greater than 1 means multi-link, and the bandwidth can reach 24M, that is, the WAN port bandwidth can be superimposed. Common applications such as P2P**, P2P**, etc.

Single link**: Right-click >> Save Target As to save a file locally. This kind of **is point-to-point**, and can only go through a fixed WAN port, so the **rate is 500kbps (4Mbps) or, it cannot be superimposed.

Web page. Generally, it is a single link, and the maximum bandwidth of a WAN port can only be experienced.

It should be that your multi-WAN enterprise router is relatively low-end, and the better enterprise router can be used both. In addition, the IP addresses assigned to the multi-WAN port routers by the AB router cannot be the same network segment.

By default, the multi-WAN interface router is in master-slave mode, that is to say, one is in the working state, and the other is in the backup state, and only when the master interface is disconnected and the slave interface can communicate. You can configure the WAN interface to load balance. In addition, the network segments of the two higher-level routers should be different.

This is actually very simple, generally causing 2 ports to not be used at the same time is generally a conflict, and IP address conflicts, or network segment conflicts will cause one of the ports to not get up, so you can check the logs first, what is the cause. If the IP address is caused by the IP address, then when you plan the network, plan the two ports into different network segments.

Tool Materials: Taking a TP-Link router as an example, there are three ways to correctly set the WAN port of the router.

The first way: access the Internet through broadband dial-up, enter the password to activate the broadband service, and then you can complete the setting.

1. Select broadband dial-up Internet access.

2. Enter the broadband password.

3. Click to connect to access the Internet.

1. Select the option to get IP address automatically.

2. Click Save to complete the settings, and then you can surf the Internet.

The third way: set a fixed IP, which is suitable for users who open a public IP, and enter the public IP, subnet mask, gateway and other information provided by the operator to access the Internet.

1. Select a fixed IP address.

2. Enter the IP information provided by the operator.

3. Click Save, complete the settings, and you can go online.
