Remote access to the company's internal machines using peanut shells?

After studying peanut shells for a long time, I still don't understand ::
Assume that the company is in City A and the traveling staff is in City B. B wants to access a machine (A) in Lan ):

1. Is it true that both computer B and computer A must be installed with peanut shells and run simultaneously. Are they all online ??
2. If B can be authorized to access a, how can I access a folder on a machine's hard disk?
3. Can machine B access other machines in LAN A (without peanut shells installed )?
4. How does machine B access other machines in Lan ??

The role of the peanut shell is simply to expose the Intranet machine to the Internet, so

1. Is it true that both computer B and computer A must be installed with peanut shells and run simultaneously. Are they all online ??
WHO provides the service, that is, who is accessed must be installed, or cannot find
2. If B can be authorized to access a, how can I access a folder on a machine's hard disk?
FTP or remote control
3. Can machine B access other machines in LAN A (without peanut shells installed )?
Normally not, But B can be used as the stepping stone, such as terminal services.
4. How does machine B access other machines in Lan ??
Same as above

If a does not need to access B, and B does not need to be installed, A is OK,

1/install access a, and B does not need to be installed (Port ing is also required for Intranet. For details, see the help of peanut shells)
2/To access the folder, you must install remote control or FTP.
3/A create a VPN Server and access it through VPNString 7
4/same as above

1. Is it true that both computer B and computer A must be installed with peanut shells and run simultaneously. Are they all online ??
^
No. You need to install peanut shells on the gateway computer.

2. If B can be authorized to access a, how can I access a folder on a machine's hard disk?
................................................
VPN

3. Can machine B access other machines in LAN A (without peanut shells installed )?
^
Yes

4. How does machine B access other machines in Lan ??
^
VPN, and then it is the same as the LAN.

Who is accessed who installed peanut shells, peanut shells can be applied to the TP-LINK r410 router, after the resolution B access r410 This router, the specific access to which PC needs to see how the router port ing settings, if port 80 of 10.1.4.5 is mapped, the Web site page set up on the 10.1.4.5 server is displayed after you access the domain name resolved by the peanut shell using the HTTP protocol; if the peanut shell is directly applied to a host, the fixed host is the opposite question;
· According to your application, you can consider setting up a VPN service in the company's network. However, currently, the user-end connection of the VPN does not seem to be able to establish a connection with the server based on the domain name, however, you can query the IP address of the server through the resolved domain name to access the VPN Server Based on the address. This ensures that your shared directory is accessed;

String 2

You can also install a peanut client on a client on the company's Intranet, set up a WWW Service on the client, and display the file list to map different Intranet shared directories to the WWW Service's heel directory, it is best to integrate the WWW Service into the system account verification; otherwise, data security cannot be guaranteed; likewise, FTP service can be used;
· If your company can obtain a public address and the address is a fixed address, it can be easily implemented without the need for peanut shells;

Port ing is acceptable. If you do not need port ing, you can use a software called vnn to install both the visitor and the visitor.
It is not as stable as using www.3322.org with peanut shells/faster.
