Type a number between 1 and 15 as the Metric value. This represents the number of routers between your network and the destination.
DG834G Reference Manual • Advertisement Period: The Advertisement Period is how often the Router will advertise (broadcast) its UPnP information. This value can range from 1 to 1440 minutes. The default period is for 30 minutes. Shorter durations will ensure that control points have current device status at the expense of additional network traffic. Longer durations may compromise the freshness of the device status but can significantly reduce network traffic.
Chapter 8 Virtual Private Networking This chapter describes how to use the virtual private networking (VPN) features of the Wireless ADSL Modem Router. VPN communications paths are called tunnels. VPN tunnels provide secure, encrypted communications between your local network and a remote network or computer. See “Virtual Private Networking (VPN):” on page A-1 to learn more about VPN.
DG834G Reference Manual Overview of VPN Configuration Two common scenarios for configuring VPN tunnels are between a remote personal computer and a network gateway and between two or more network gateways. The DG834G supports both of these types of VPN configurations. The Wireless ADSL Modem Router supports up to five concurrent tunnels. Client-to-Gateway VPN Tunnels Client-to-Gateway VPN Tunnels provide secure access from a remote PC, such as a telecommuter connecting to an office network.

DG834G Reference Manual — Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many broadband ISPs restrict access by only allowing traffic from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single PC connected to that modem. If this is the case, you must configure your router to “clone” or “spoof” the MAC address from the authorized PC. Refer to “Manually Configuring Your Internet Connection” on page 3-14.

DG834G Reference Manual A Dynamic DNS (DDNS) service allows a user whose public IP address is dynamically assigned to be located by a host or domain name. It provides a central public database where information (such as email addresses, host names and IP addresses) can be stored and retrieved. Now, a gateway can be configured to use a 3rd party service in lieu of a permanent and unchanging IP address to establish bi-directional VPN connectivity. To use DDNS, you must register with a DDNS service provider.
