How to set up a router to implement cross network segment file sharing

Why install two routers? Is there a controllable Layer 3 switch in between?

What is the router subnet?

You can access the NAS normally because you are in the same subnet CIDR block, this kind of access is the same as simple sharing, and cross-network segment access depends on how your router 2 is set up and whether you allow Router 1 to access the network segment. Cisco routing should have this function, but as long as it encounters a customized router for telecommunications, it is difficult to say.

It is recommended that you take a look at the ip** and route tutorials, which will not be detailed. Most routers now have a route function, and Cisco also has one.

But I can't figure out why you want to install two routers, if it's because the subnet IP is not enough, you can use it completely.

You can have 2 network segments.

First of all, it's definitely not a router, you can make a rip connection between 2 routers, so you can access it.

Specifically: a router port

Another router

That's it.

It's very simple. If your router has two LAN ports, then it's fine.。。 Configure the IP of two network segments on the two ports, that is, one of the connected ports is also set to be different) The same is true.

Then go out together on the router... In this way, different network segments can communicate

1. When the same network segment is in the same network segment, the firewall defaults that this network segment belongs to the local area network, and the default security network firewall is not truncated. But after you change to two network segments, it doesn't recognize this, and it thinks that these are two different networks, and you have to access it to add it to the trusted area.

2. How to set up the specific firewall, you can see according to your own firewall. If you can ping each other, it should be no problem to open a shared folder, but the firewall is sometimes very weird, and it also plays a certain role in disrupting the network when you go up and deactivate it.

3. It is recommended that when accessing the shared folder, it is still "the IP address of the computer you want to access" so that the access is faster. If you can't access it, then you can use the router as a switch, and you don't need to look at the second land travel function.

1. First of all, open the router management interface--- ** rule --- dmz, and enter the intranet.

The address of the server or network printer.

2. When PC A accesses the resources shared by PC B or network printers on the server, it needs to use the IP address of the WAN port of Router Router2.

3. Open the router management interface, click on the **rule --- virtual rib device, and the vertical reputation is as shown below.

4. Then click on the orange friend"Add a new entry to the remainder segment"。

5. At this time, PC A accesses the web server under Router2.

It is the WAN port address of router2 plus port 8080.

to access it. <>

You can have 2 network segments First of all, it is definitely not a router, you can make a rip connection between the 2 routers, so that you can access it.

Specifically: a router rip on a router port

Another router rip would do just fine.

If there is a route, it can be shared across network segments!

1. First of all, open the router management interface--- ** rule --- dmz, and enter the server or network printer address of the intranet.

2. When PC A accesses the resources shared by PC B or network printers on the server, it needs to use the IP address of the WAN port of Router Router2.

3. Open the router management interface and click on the rule --- virtual rib server, as shown below.

4. Then click"Add a new entry"。

5. At this time, PC A can access the web server under Router2, which can be accessed by adding port 8080 to the WAN port address of Router2.

There will be problems with the settings.

Wireless routers A-D are connected in parallel under router A, but A-D cannot be in the same network segment as follows:

A: LAN port settings, B: LAN port settings, C: LAN port settings, D: LAN port settings,

You can do static routing, this is simple.

Each of your slave router has a static IP of the main route, and all the slave router is connected to the WAN port!

In fact, this kind of planning is a network segment, just plan well, don't conflict!

Example: Primary route: The machine gateway connected to this is all set, and the machine IP is unique, except for the following subordinate route, the gateway does not need to be configured.

From Route: The machine gateway connected to this is all set, and the machine IP is the only from the route The machine gateway connected to this is all set, and the machine IP is the only one you know???

Your text description is inconsistent with the description on the map, and the IP of the LAN port of the wireless router ABCD is in the same network segment, as if it can't be realized, I redrew a picture according to your ideas, you try it (I don't have multiple routers, no verification).

Are you in the same place for both segments, or are they in two different places?

If it is in the same LAN, you only need to set the routing table, and if it is two different places, the route of one side needs to support VPN function, such as pptp, l2tpipset, etc.

Apply for a free domain name, activate it in the route, and create a tunnel name and passwordThe other party only needs to suggest a VPN dial-up address to that free domain name, and then use the tunnel name and password when dialing the number.

After dialing in, the two network segments can be interconnected and shared.

No, you can't. The IP address of the route can only be one... n 1 to 254 any one ...

When there are 2 routes. It can be different nets. but not each other ...

It's like monogamy ... It's impossible to sleep with 2 milks.。。。

Haha,, let's talk about it first.

The premise is that your router should support port customization, and multiple LAN ports can be configured with different IP segments. At present, home routers generally do not support this function, UBNT small routers can support it, and other brands such as Cisco, Huawei, etc. need enterprise-level routers.

If you need to be supported by a router, you can't use it for ordinary home use.

Can your route be divided into VLANs? Simple routes don't have this feature.

The network card sets up multiple IP addresses with different network segments, and different IP addresses can access each other's computer networks across network segments.

Internet access is on. If the following route is a home router, use it as a switch to achieve network reachability, which is the easiest way.

Buying a storage router solves the problem.

Port mapping.

Why are you doing so many routers?

If you need to isolate the intranet, you can use it on the switch.
