Be sure to set your computers to be DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers on, they will automatically load the proper TCP/IP settings provided by the DIR-825. The DHCP Server will automatically allocate an unused IP address from the IP address pool to the requesting computer. You must specify the starting and ending address of the IP address pool.

Virtual Server
The DIR-825 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 (Local Area Network).
The DIR-825 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked with the DIR-825 are invisible to the outside world. If you wish, you can make some of the LAN computers accessible from the Internet by enabling Virtual Server. Depending on the requested service, the DIR-825 redirects the external service request to the appropriate server within the LAN network.
The DIR-825 is also capable of port-redirection meaning incoming traffic to a particular port may be redirected to a different port on the server computer.
Each virtual service that is created will be listed at the bottom of the screen in the Virtual Servers List. There are pre-defined virtual services already in the table. You may use them by enabling them and assigning the server IP to use that particular virtual service.
