and point to your router, which then needs to deliver all traffic to the private IP addresses used by
yourPCs. Please see the WAN configuration section of this manual for more information on NAT.The
device can be configured as a virtual server so that remote users accessing services such as Web
or FTP services via the public (WAN) IP address can be automatically redirected to the local servers
on the LAN network. Depending on the requested service (TCP/UDP port number), the device
redirects the external service request to the appropriate server within the LAN network.
