    Configure Link: IP Static Routes A static route identifies a manually configured pathway to a remote network. Unlike dynamic routes, which are acquired and confirmed periodically from other routers, static routes do not time out. Consequently, static routes are useful when working with PPP, since an intermittent PPP link may make maintenance of dynamic routes problematic.

The default gateway • must be located on a network connected to your Netopia Gateway configured interface. • Metric: Specifies the hop count for the static route.

    Configure With this topology, you configure the embedded administration ports as a first task, fol- lowed by the Pinholes and, finally, the NAT Default Server. When using both NAT pinholes and NAT Default Server the Gateway works with the follow- ing rules (in sequence) to forward traffic from the Internet to the LAN: If the packet is a response to an existing connection created by outbound traffic from a LAN PC, forward to that station.

    TR-064 is a LAN-side DSL Gateway configuration specification. It is an extension of UPnP. It defines more services to locally manage the Netopia Gateway. While UPnP allows open access to configure the Gateway's features, TR-064 requires a password to execute any command that changes the Gateway's configuration.

  • Page 102: Advanced -> Ethernet Bridge

    Link: Advanced -> Ethernet Bridge The Netopia Gateway can be used as a bridge, rather than a router. A bridge is a device that joins two networks. As an Internet access device, a bridge connects the home com- puter directly to the service provider’s network equipment with no intervening routing func- tionality, such as Network Address Translation.

    An SSID differentiates one wireless network from another, so all access points and all devices attempting to connect to a spe- cific network must use the same SSID. Netopia Gateways support up to four SSIDs. SSIDs are also sometimes referred to as Network Names because they are names that identify wireless networks.
