Virtual server

With the IBM High Rate Wireless LAN Gateway, you can make some servers
on the LAN accessible to users through the Internet. These servers are called
Virtual Servers.
Only one server for each IP service can be run (for example, http or ftp). Each
service is defined by the service type (TCP or UDP) and the TCP or UDP
number, respectively.
To add a Virtual Server, do the following:
1. Click Advanced Configuration, and then click Virtual Server
Configuration to display the Virtual Server table.
This table displays the status of the Virtual Servers on the LAN. You can
enable or disable virtual server by selecting Enable or Disable from the
pull-down menu at the top of the table.
Note: You must click Apply for the enabling or disabling to take effect.
2. To add a Virtual Server, click Add.
v Virtual Server: Enable or disable the Virtual Server on the LAN. Only an
enabled server can be accessed through the Gateway from the Internet.
v Global Port: TCP or UDP port number used by the Gateway on the
Internet-broadband port. This is the port number visible to users in the
Internet, and is also known as the External Port Number.
v Local IP: IP address of the server computer on the LAN.
