Security and Performance

Security suggestions

• If you don’t want to let anyone can register a VPN account on your VPN server,please disable “Allow Register VPN Account from Network”. By default, the feature is diabled.
  
  
• If you don’t care about the VPN network speed, please use SSL/TLS protocol to connect VPN-X server.
  
  
• Change the VPN-X server listening port to some other unpopular port number. By default, VPN-X server listen on following ports: 25000(UDP/TCP) 25443(TCP).
  
  
• Generate your own SSL certification or key. BirdsSoft can provide this generation certification service for customers. Because this is a very special requirement, this service is not free. Most users need not care about how to generate SSL certification, because the built-in certification is safe until you think you are doing business with the FBI.

You can read this section to know some VPN-X parameters for security.

Performance

This section just want to tell you, VPN-X is a high performance VPN solution. Better hardware machine(new PC, for example dual-core CPU) or network environment will get better performance. 

The following data is our test result.

Test environment:

Windows XP * 2
CPU AMD 1700+ * 1
CPU AMD 3000+ * 1
Memory 1G * 2
LAN speed:100Mbit/s, the real transfer speed is 64Mbit/s
VPN-X: 2.2.1.26

• In a LAN environment, the speed ranks: UDP>TCP>SSL
  
  
• If you have a better machine and network, the test data should be better.
  On the Internet, the VPN transfer speed should be 92%~500% or higher of the WAN speed, because the VPN will compress the network data before transfer on the Internet. After the data reaches the target machine, the data will be uncompressed automatically.
  
  
• UDP is preferred and default, if you care about VPN speed, but sometimes if your internet connection is not stable, TCP or TCP (SSL) is a better choice for VPN speed.
