How can two LANs access each other

Don't use sharing, sharing in win98, win2000, winxp and other versions of different versions of the processing is different, there are serious security vulnerabilities.

It is recommended to use an FTP server to share files, for example, if you install a SERV-U software, you can set up many accounts in SERV-U (which can have nothing to do with the system account), set up no account to be able to see those directories, write those directories, you can set whether to allow deletion and other permissions, and even set the speed of **.

A strategy for mutual access to local area networks.

The book server uses two network cards and is assigned to the IP of the two network segments. This makes it accessible. If you want to access the Internet, fill in the gateway and DNS of one of the networks, and leave the other one blank. That's pretty much what you said.

Suppose your server has two network cards with IP addresses from different network segments, and you have only these two network segments in your environment, and all devices are in these two network segments.

You don't need to do anything extra, and devices in both network segments can access the server. Routing refers to communication between different network segments. Since the server and the device are on the same network segment, there is no need to set up a route.

However, if a third segment appears, then the route must be set up on the network device and the server.

Static routing is set to enable the pinging of different network segments of the first-level router and the second-level router, and the L2 router must support the routing mode to achieve this function.

Routes between different network segments are required.

In fact, it is much easier to achieve full interoperability between the two networks.

1. First of all, you need to buy a router, which is very cheap, usually dozens to a hundred.

2. Let's assume that the network segment of network A is, the network segment of network B is, the router address is, the HTTP server of A is set, and the HTTP server address of B is set.

3. Connect the networks of the two network segments through the router Minzhi, and access the switches of the two networks, network A --- router --- network B (note that it cannot be plugged into the WAN port of the router Sun).

Access the router through the machine on network B, find the routing table in it, and add a routing table

ip: Subnet Mask: Gateway is set to:

After saving and exiting, set the subnet mask of all machines in the LAN to and the gateway to .

4. Try to pass.

Or access try If there is a modem with a route, then take the scatter to achieve the above functions, the connection is a little different, it should be:

The modem --- network A--- network B or connected to network B, and other settings are the same as routers.

If the FTP server is the same, you don't need to set it, if not, please set it to.

If you want two networks to interconnect, you only need to change the server IP address to the IP of the original network segment, and then change the routing table to the following:

Generally, there will be a table in the router.

If you don't have the above table, please add it!
