3.5 Virtual Server
The router can be configured as a virtual server so that remote users accessing
Web or FTP
services via the public
IP address
can be automatically redirected to local servers in the
LAN.
The router firewall feature filters out unrecognized packets to protect your
LAN
network so all
networked computers connected to the router are invisible to the outside world. If you wish, you can
make some of the networked computers accessible from the Internet by enabling Virtual Server.
Depending on the requested service, the router will redirect the external service request to the
appropriate server within the
LAN
network.
