In addition to adding these WDS Connections, Site C & D will need a default gateway address configured so that the
module can determine where to send traffic destined for the other networks. Also because Site A does not know how to
get to Network’s 192.168.5.0 and 192.168.6.0 it requires rules to confirm the routing paths. A default gateway and one
routing rule could be configured but it is easier to configure two routing rules as shown in the example below.
Figure 50 - Site A Routing Rules
The first routing rule specifies 192.168.5.0 as the Destination with a Netmask of 255.255.255.0, (network address
range of Site B) – because the last byte of the destination IP is zero, this refers to the network (192.168.5.1 –
192.168.5.254) as opposed to an individual host IP. The same rule specifies the address 192.168.0.3 as the
gateway address. The routing rule effectively tells the WI-MOD-E that any traffic destined for the network
192.168.5.X should be forwarded to Site B via WDS link address 192.168.0.3.
The second routing rule is similar except the destinations IP address range is 192.168.6.0 with a Netmask of
255.255.255.0, indicating all traffic for the 192.168.6.X network will be routed through the WDS link address
192.168.0.4. This is the WDS Router IP address that Site C has been configured with for its WDS link to Site A.
For more information on routing rules, refer to the section 3.18 - “Routing”.
Unit C & D require some sort of routing rule that will determine how it communicates to networks outside of its
configuration.
Similar routing rules as shown above could be configured to direct traffic to
these other networks however if only one routing path is required a default
Gateway address can be configured on the Network page.
