Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual
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-245U-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.
3.16 Wireless Message Filtering
When configured as a Bridge, the BU-245U-E will transmit all broadcast messages appearing at its wired Ethernet port.When the BU-245U-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 unnecessar y
broadcast traffic sent over the radio link, will increase available bandwidth for data.The BU-245U-E has a filtering feature to help reduce
unnecessary wireless transmissions and enhance security.
The BU-245U-E may be configured to reject or accept messages to and from certain Addresses.To accept wireless messages from particular
devices a “Whitelist”of Addresses must be made. Alternatively to reject messages from particular devices, a “Blacklist” of Addresses must be
made. Filtering applies only to messages appearing at the wired Ethernet port of the configured BU-245U-E.
The Filter comprises of three lists: MAC Addresses,IP Address/Protocol/Port and ARP Filters. Each list may be set as either a Blacklist (to block
traffic for listed devices and protocols), or as a Whitelist (to allow traffic for listed devices and protocols).The Filter operates on four rules listed
below.
• The MAC Address filter is always checked before the IP Address filter.
• If a message matches a MAC filter entry, it will not be subsequently processed by the IP filter. If the MAC filter list is a Whitelist,the message
will be accepted. If the MAC filter list is a Blacklist,the message will be dropped.
• The MAC address list checks the Source address of the message only.
