INTELLIGENT BRIDGE
The intelligent bridge uses filters to only allow traffic to flow between itself and an access controller. Traffic is filtered
as it is received by the upstream, downstream, or wireless ports. Each port has its own specific set of filters. Filters
apply only to data being received by the port (incoming traffic).
Upstream Port Filter (incoming traffic)
Accepted
• Any traffic from the access controller.
• Certain address management protocols (ARP, DHCP) regardless of their source address.
• HTTPS traffic regardless of its source address. (This permits local or remote management stations to
access the LPS-20x management tool.)
• Any traffic addressed to the LPS-20x.
• All broadcast traffic.
Blocked
• All other traffic is blocked. This includes NetBIOS traffic regardless of its source/destination address.
Downstream Port Filter (incoming traffic)
Accepted
• Any traffic addressed to the access controller. If you are using multiple daisy-chained LPS-20xs, all
should forward traffic to the same access controller.
• HTTPS traffic regardless of its source address. (This permits local or remote management stations to
access to the LPS-20x management tool.)
• Any traffic addressed to the LPS-20x.
• Certain address management protocols (ARP, DHCP) regardless of their source address.
• All broadcast traffic.
Blocked
• All other traffic is blocked. This includes NetBIOS traffic regardless of its source/destination address.
Wireless Port Filter (incoming traffic)
Accepted
• Any traffic addressed to the access controller.
• Any traffic addressed to the LPS-20x. Note that to access the management tool wirelessly, the appropri-
ate security setting must be enabled on the Management tool page. Wireless client stations should have
the
LPS-20x configured as their default gateway. This ensures that outgoing traffic will be sent to the LPS-20x
which will then forward it to the access controller.
• Certain address management protocols (ARP, DHCP) regardless of their source address.
• All broadcast traffic.
Blocked
• All other traffic is blocked. This includes NetBIOS traffic regardless of its source/destination address.
HTTPS traffic not addressed to the LPS-20x is also blocked which means wireless client stations cannot
access the management tool on other LPS-20xs.
