Virtual Server
This screen is used to redirect remote users requesting services (e.g., Web,
FTP) on your local network from the Barricade’s public IP address to
internal host servers configured with private IP addresses. Depending on
the requested service (TCP/UDP port number), the Barricade redirects
the external service request to the appropriate server (located at another
internal IP address). This secures your network from direct attack by
hackers, and provides more flexible management by allowing you to
change internal IP addresses without affecting outside access to your
network.
