Elpro Technologies 450U-E Wireless Ethernet Modem & Device Server User Manual
Rev Version 1.4.0 www.cooperbussmann.com/wirelessresources 39
The configuration for Site B is shown below in Figure 43. The WDS is configured with a Virtual Access Point for the virtual
clients configured at Sites A & C. The Encryption Method and key are configured the same as the main network for
simplicity.
The WDS configuration for Site A & Site C will be exactly the
same as Site B except the Connection Mode will need to be
.
The main network configuration settings for all sites will all be
the same for each site (as shown).
This setup can be replicated many times which will allow
Roaming Stations full connectivity across the network.
IP Routing 3.10
When a 450U-E receives an IP frame that is destined for an IP address on a different network, it checks if the network
address matches the network address of one of its own interfaces (i.e. hard-wired Ethernet, or wireless Ethernet, or WDS)
and forwards the frame appropriately. However, if the IP network address does not match the network address of any of
its interfaces, the 450U-E will forward the frame to its default gateway. In this case it is assumed that the default gateway
has a valid route to the destination.
In some cases, it is not practical to have just one default gateway (i.e. routed wireless networks with more than two 450U-
E routers; and in some cases when WDS router interfaces are used). If more than one -
450U-E allows for up to 100 routing rules to be configured. A routing rule specifies a destination network (or host) IP
address and the corresponding next-hop router that messages for the specified destination will be forwarded to. It is
assumed that the next-hop router (or gateway ) will then deliver the data to the required destination (or forward it on to
another router that will).
