Use P2P will seriously occupy network bandwidth and it can change its service port. So the MIS engineer not only set the service port in Service, but also need to set IM / P2P Blocking P2P Blocking. 117
Chapter 10 Virtual Server Virtual Server The real IP address provided from ISP is always not enough for all the users when the system manager applies the network connection from ISP. Generally speaking, in order to allocate enough IP addresses for all computers, an enterprise assigns each computer a private IP address, and converts it into a real IP address through SMC BR21VPN’s NAT (Network Address Translation) function. If a server that provides service to WAN network is located in LAN networks, external users cannot directly connect to the server by using the server’s private IP address. The SMC BR21VPN’s Virtual Server function can solve this problem. A Virtual Server has set the real IP address of the SMC BR21VPN’s WAN network interface to be the Virtual Server IP. Through the Virtual Server function, the SMC BR21VPN translates the Virtual Server’s IP address into the private IP address in the LAN network. Virtual Server owns another feature know as one-to-many mapping. This is when one real server IP address on the WAN interface can be mapped into four LAN network servers provide the same service private IP addresses. This option is useful for Load Balancing, which causes the Virtual Server to distribute data packets to each private IP addresses (which are the real servers) by session. Therefore, it can reduce the loading of a single server and lower the crash risk. And can improve the work efficiency. 118
