WRT-2110


Ch 6. Routing

While the WRT-2110 includes a standard (static) routing table, this feature can be completely ignored if you do not have a router in your LAN.

If you DO have a router, it is necessary to configure BOTH the Router and the Routing table in the WRT-2110 correctly, as described in the following sections.

See Routing Example later in this Chapter for an example of configuring both the WRT-2110 and the Router.

 

6.1 WRT-2110 Configuration

The routing table is accessed by the Routing link on the LAN screen. An example screen is shown below.

Figure 22: Routing Screen

Using this Screen

Any existing entries are listed. To view and edit the details of an existing entry, select it, and click "Get Data". After making an changes, click the "Update" button to save your changes.

To add a new entry, click "Clear Form", enter your data, then click the "Add" button.

Routing Table Data

An entry in the routing table is required for each LAN segment on your Network, other than the segment to which this device is attached. The data in the Routing Table is as follows.

Destination
IP Address
The network address of the remote LAN segment.
For standard class "C" LANs, the network address is the first 3 fields of this Destination IP Address. The 4th (last) field can be left at 0.
Network Mask
The Network Mask used on the remote LAN segment. For class "C" networks, the standard Network Mask is 255.255.255.0
Gateway
IP Address
The IP Address of the Router on the LAN segment to which this device is attached. (NOT the router on the remote LAN segment.)
Interface
Select the appropriate interface - LAN (Internal LAN) or WAN (External LAN or WAN) from the drop-down list.
Metric
The number of routers which must be traversed to reach the remote LAN segment. The default value is 1.

 


6.2 Router Configuration

It is essential that all IP packets for devices not on the local LAN be passed to the WRT-2110, so that they can be forwarded to the external LAN, WAN, or Internet To achieve this, the local LAN must be configured to use the WRT-2110 as the Default Route or Default Gateway.

Local Router

The local router is the Router installed on the same LAN segment as the WRT-2110. This router requires that the Default Route is the WRT-2110 itself. Typically, routers have a special entry for the Default Route. It should be configured as follows.

Destination IP Address
Normally 0.0.0.0, but check your router documentation.
Network Mask
Normally 0.0.0.0, but check your router documentation.
Gateway IP Address
The IP Address of the WRT-2110.
Metric
1

 

Other Routers on the Local LAN

Other routers on the local LAN must use the WRT-2110's Local Router as the Default Route. The entries will be the same as the WRT-2110's local router, with the exception of the Gateway IP Address.


6.3 Routing Example

Figure 23: Routing Example

For the LAN shown above, with 2 routers and 3 LAN segments, the required entries would be as follows.

For the WRT-2110's Routing Table

The WRT-2110 requires 2 entries as follows.

Entry 1 (Segment 1)

Destination IP Address
192.168.1.0
Network Mask
255.255.255.0
(Standard Class C)
Gateway IP Address
192.168.0.100
(WRT-2110's local Router)

Entry 2 (Segment 2)

Destination IP Address
192.168.2.0
Network Mask
255.255.255.0
Gateway IP Address
192.168.0.100

 

For Router A's Default Route

Destination IP Address
0.0.0.0
Network Mask
0.0.0.0
Gateway IP Address
192.168.0.1 (WRT-2110's IP Address)

 

For Router B's Default Route

Destination IP Address
0.0.0.0
Network Mask
0.0.0.0
Gateway IP Address
192.168.1.80 (WRT-2110's local router)
