Chapter 1 Virtual Server Concept
1.1 Why Need Virtual Server?
The NAT (Network Address Translation) shared internet connection and
protect internal LAN, so it caused the server or host in LAN cannot be
accessed from WAN. And some on-line games, BT download need to mapping
the LAN port to WAN for accessing, but as normal, the access from WAN
would be blocked by router.
1.2 What Is Virtual Server?
Virtual Server (Port Mapping) is a feature for allowing the access from WAN to
LAN. When some clients try to access the server or host in LAN via WAN IP
address, the router will forward to the appointed server/host base on virtual
server setting, and the user cannot feel any difference.
