Many enterprises have hosted servers with one or more Internet Data Centers(IDC). When doing the daily maintenance, the owner of the hosted servers frequently encounter the following problems:
1. Need to enable the RDP protocol on the hosted server. This exposes the server to the Internet without protection.
2. Some hosted servers have no public IP address. One has to login to the server with public IP first and then access those servers behind it.
3. Transferring data between admin's PC and the servers is not simple. Periodically downloading logs or back up DB is not possible or hard to do.
Advantages
1. No need to require the server with public IP to listen any TCP ports for the public IP address.
2. No matter the server has public IP or not, the admin can directly access them from their own PC.
3. Built-in VNN-File Express module can be used to setup periodic file/folder transfer between admin's PC and the hosted servers.
