Cooper Bussmann Wireless Ethernet & Device Server BU-945U-E 802.11 DSSS User Manual

An alternative to adding routing rules to the BU-945U-E in this example would be for each device on LAN A that needs to communicate with LANs B and C to have independent routing rules specifying the BU-945U-E clients at B and C as gateways to those networks.

The routing rules for the Access Point in the above example are shown below. The first entry shows the route to LAN B. The gateway for the route to LAN B is configured as the wireless IP address of the BU-945U-E client connected to LAN B. The destination for the route is configured as the network address of LAN B. Because the host id of the destination IP address is 0, it specifies a network address. Consequently, any traffic received at the Access Point with destination IP address 169.254.109.x (where x is any host id) will be forwarded to the BU-945U-E at LAN B.

Devices on LAN B & LAN C that needs to send messages back to LAN A will need to have their Gateway addresses directed to the BU-945U-E on their respected networks. i.e., a LAN B device needs to send data back to LAN A. The Gateway address will need to be configured as 169.254.109.40 as this is the IP address of the wired side of the LAN B BU-945U-E. Any message coming in with a 192.168.0.X IP address will be directed across the wireless interface to LAN A.

The Routing Rules configuration page can be accessed by selecting the “Routing” link on any of the configuration web pages. Up to 30 routing rules may be added to each BU-945U-E. The table below summarizes the configurable parameters of a routing rule.

Name

A name to describe the routing rule (Max 32 characters)

Destination

The destination network (or host) IP address (to specify a network address set the host address to 0. i.e., for an

 

IP address 192.168.0.0 with Netmask 255.255.255.0 would specify a destination network, while 192.168.0.16

 

specifies a destination host).

Subnet Mask

The subnet mask for the destination network.

Gateway

The IP address of the next-hop router for the specified destination.

Enabled

Check this box to enable the rule. You can Uncheck the box to disable a routing rule without needing to re-enter the

 

information at a later time.

Note: Entering dedicated Ethernet Routes can also be added to the wired Ethernet LAN in place of generating / adding routing rules into the modems.

3.14 Wireless Message Filtering

When configured as a Bridge, the BU-945U-E will transmit all broadcast messages appearing at its wired Ethernet port. When the BU-945U-E is configured as a Router, this does not occur.

In many cases, the intended recipient of the broadcast traffic does not lie at the opposite end of a proposed radio link. Reducing unnecessary broadcast traffic sent over the radio link, will increase available bandwidth for data. The BU-945U-E has a filtering feature to help reduce unnecessary wireless transmissions and enhance security.
