The Fixed Nodes Filter will prevent traffic which is destined to a non-broadcast, non-
multicast, non-RangeLAN2 address from being forwarded from Ethernet to wireless.
DO NOT use this filter when using the node address overwrite feature on RangeLAN2
stations.
The Protocol Type Filters prevent traffic of a particular protocol type from being
forwarded from Ethernet to RangeLAN2. When “Other Types” is enabled, all types
other than those listed will be filtered out. DO NOT filter out the types of packets you
know RangeLAN2 nodes will need to receive. For example, if you use TCP/IP as a
protocol on your wireless nodes, do not filter IP traffic. If you have Macintosh comput-
ers on your Ethernet network that send AppleTalk traffic only to each other, you may
want to filter those packets from RangeLAN2 stations. The Protocol Type Filters
include IP, IPX, NetBEUI, AppleTalk, DECNet, and Other (none of the above).
The IPX Broadcast Filters prevent IPX broadcasts of the specified types from being
forwarded from Ethernet to RangeLAN2. Since RIP, SAP, and LSP broadcasts are of
interest to routers and not end stations, these filters can typically be turned on, saving
valuable bandwidth.
The ARP Filter Network Address and ARP Filter Subnet Mask enable IP ARP
broadcast filtering. When these filters are configured, ARP broadcasts will be forwarded
from Ethernet to RangeLAN2 only if the destination IP address is on the IP network
defined by the ARP Filter Network Address and ARP Filter Subnet Mask fields.
If you enable Filter MAC Multicast Packets, you must also configure the MAC Filter
Address and MAC Filter Subnet Mask to specify the range of multicast packets which
will be forwarded to the RangeLAN2 network. When these parameters are configured,
the Access Point will forward from the Ethernet to the RangeLAN2 network only those
hardware multicast packets whose multicast address is within the range of addresses
defined by the MAC Filter Address and MAC Filter Subnet Mask.
Broadcast Bandwidth Allocation allows you to specify the maximum percentage of
RangeLAN2 bandwidth that may be allocated for broadcast traffic. There may be cases
when you want to limit broadcast traffic. As an example, to prioritize directed packets,
you might want to reserve radio bandwidth for directed packets by setting this limit to
less than 100%.
