Virtual Servers

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’s IP address is only valid on your LAN, not on the Internet.

Attempts to connect to devices on your LAN are blocked by the firewall in the XC-DPG602.

The “Virtual Server” feature solves these problems and allows Internet users to connect to your servers, as illustrated in Figure 10.

Connecting to Virtual Servers

Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the XC-DPG602’s Internet IP Address (the IP Address provided by your ISP).

Example:

http://205.20.45.34

ftp://205.20.45.34

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 connect to your Servers. However, you can use the Dynamic DNS feature (explained later in this chapter) to allow users to connect to your Virtual Servers using a URL, instead of an IP Address.

e.g. HTTP://my_domain_name.dyndns.org FTP://my_domain_name.dyndns.org

Settings - Virtual Server

Enable	Use this to Enable or Disable each Virtual server as required.
Server Type	Select the desired Server type. If the type of Server you wish to use is
	not listed, use the Custom Virtual Server screen to define your own
	type.
LAN IP Address	Enter the IP address of the PC on your LAN which is running the
	required Server software.
	Each PC should have a fixed IP address, or have a reserved IP
	address. (See the Host IP section earlier in this chapter for details on
	reserving an IP address.)

Figure 10. Virtual Servers

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