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.
