Virtual Servers

This feature allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because:

•Your Server does not have a valid external IP Address.

•Attempts to connect to devices on your LAN are blocked by the firewall in this device.

The "Virtual Server" feature solves these problems and allows Internet users to connect to your servers, as illustrated below.

Figure 31: Virtual Servers

IP Address seen by Internet Users

Note that, in this illustration, both Internet users are connecting to the same IP Address, but using different protocols.

To Internet users, all virtual Servers on your LAN have the same IP Address. This IP Address is allocated by your ISP.

This address should be static, rather than dynamic, to make it easier for Internet users to con- nect to your Servers. If using a Static IP Address, it is entered on the "WAN" screen.

Types of Virtual Servers

The Wireless Gateway supports two (2) types of Virtual Servers:

•Pre-defined- Standard server types. The only data required is the IP Address of the server on your LAN.

•User-defined- Non-standard servers. You must provide additional information about the server.

Note: The TOTAL number of Virtual Servers which can be used at any time is 10.
