Setup Tab - DDNS

DDNS (Dynamic DNS) service allows you to assign a fixed domain name to a dynamic WAN IP address. This
allows you to host your own Web, FTP or other type of TCP/IP server in your LAN. See Figure 6-18.
Before configuring DDNS, you need to visit www.dyndns.org and register a domain name. (The DDNS service is
provided by DynDNS.org).
DDNS Service: The DDNS feature is disabled by default. To enable this feature, just select DynDNS.org from the
pull-down menu, and enter the User name, Password, and Host Name of the account you set up with DynDNS.org.
Your IP Address: The Router's current Internet IP Address is displayed here. Because it is dynamic, this will
change.
Status: The status of the DDNS function and Internet status is displayed.

Dynamic Routing
The Router's dynamic routing feature can be used to automatically adjust to physical changes in the network's
layout. The Router uses the dynamic RIP protocol. It determines the route that the network packets take based on
the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing
information to other routers on the network. See Figure 6-19.
Working Mode: Select Gateway mode if your Router is hosting your network's connection to the Internet. Select
Router mode if the Router exists on a network with other routers, including a separate network gateway that
handles the Internet connection. In Router Mode, any computer connected to the Router will not be able to
connect to the Internet unless you have another router function as the gateway.
RIP (Routing Information Protocol): The Router, using the RIP protocol, calculates the most efficient route for the
network's data packets to travel between the source and the destination, based upon the shortest paths.
Receive RIP versions: Choose the RX protocol you want for receiving data from the network. (None, RIPv1, RIPv2,
Both RIPv1 and v2).
Transmit RIP versions: Choose the TX protocol you want for transmitting data on the network. (None, RIPv1,
