In what ways does IPTunnelManager differ from other similar programs?
After we had a long search though the Internet trying to find a program for compressing and securing our network traffic between a client application and a DBMS (MS SQL Server 2000), we came to the conclusion that there was no software that suited our task and we would have to develop it on our own. The main aims in developing such software were the following: as easy to use as possible, universal in its use, highly flexible and effective, secure. And so we came up with "IPTunnelManager" that mainly differs from similar programs in the following ways:
- Easy to use due to the interactive application with a well designed user interface.
- A separate service application for Windows NT/2000/2003/XP.
- One and the same application both for the client and for the server.
- Flexible and convenient tunnel configuration. Much easier configuration. For example, to let a new client connect, it is enough to add his address to the "Access list", yet even this may be unnecessary if it is an internal network and client IPTunnelManager.
- Testing in practice proved the high security and performance of the product.
- Possibility to switch to alternative servers and determining maximal channel capacity, all that contributes to the flexibility and security of your networks.
- Much better prices due to a more effective management for company's expenses and experience in his field.
How does the program influence the data transfer channel capacity?
The channel capacity very much depends on the type of data being transferred: the most important factor is the average packet size transferred over the network. Our tests revealed that the rate remains the same on 10-Mbit networks with an average packet size of 8 Kbytes. The data transfer rate relatively increases on channels with less capacity (not more than 128 Kbit/sec) due to data compression.
Is it always necessary to add the address of a client to the "Access list"?
No, it is not. But you must specify other IPTunnelManagers in the "Access list" so that the program could apply a special exchange protocol in that case.
Why does the "Ratio to server %" field have negative values in it?
If IPTunnelManager unpacks compresses data for this direction (from the client to the server or from the server to the client) the "Ratio" index will have a negative value for the corresponding direction.
In the "Server description" and "Client description" forms there are fields for specifying "Host" and "Address". What is the difference between them?
You should specify only one of these fields. If you know the name of the host and it will be available (for example, the network name of a computer in local area networks), it is enough just to specify the "Host" field. Though, as a rule, it is the "Address" field that is specified. The IP address of a computer is entered in this field (in the format 127.0.0.1).
What does the IsIPTunnelManager checkbox mean in the "Server description" and "Client description" forms and what is it for?
In the "Server description" form it means that the connection will be established with another IPTunnelManager and the traffic can be encrypted and compressed in this case. In the "Client description" form the "IsIPTunnelManager" checkbox means that another IPTunnelManager will be the client.
IMPORTANT: a secure connection and traffic compression are possible only between two IPTunnelManager.
