Virtual Servers
This feature allows you to make a server on your LAN accessible to Internet users.
Normally, Internet users would not be able to access a server on your LAN because:
♦
Any Server on your LAN does not have a valid external IP Address.
♦
Attempts to connect to devices on your LAN are blocked by the firewall in the
Barricade.
The "Virtual Server" feature solves these problems and allows Internet users to con-
nect to your servers, as illustrated below.
Figure 9: Virtual Servers
Note that, to Internet users, ALL of your Virtual Servers seem to have
the same IP Address. This IP address is allocated by your ISP.
To make it easier for Internet users to connect to your Virtual Servers, it is better to
have your ISP assign you a fixed IP Address.
To Use the Virtual Server feature
1. Install and configure the desired Server software on a PC on your LAN.
2. Enable the desired Server type on the Virtual Server screen on the Barricade,
and enter the IP Address of the system running the Server software.
3. Advise users of the IP Address required to connect to the Virtual Servers. This
IP Address is supplied by your ISP, and is shown on the Barricade's Virtual
Server screen.
