At a Hospital we have some GE Dash 4000 units that use our wireless network in order to communicate with their seperate network. These devices are all 802.11b and they work off broadcast. The way they work is that each unit sends a broadcast every 45 seconds. Anyone that sees that traffic can make a unicast communication with that device to monitor the device's output, in this case patien vital signs. Now, this works fine when the devices are connected to the the GE wired network, but not when the devices are connected to our wireless network.
The devices on wireless can see all the other devices, so they are receiving broadcast traffic, but non of the other devices can see the wireless units.
When checking the datapath session, I can see broadcast traffic from/to the host.

The clients state that they noticed the issue happen about 3 months ago, which is about the time when we replaced all the AP70s in that site with AP105s. Anyone have any clue what could be causing the broadcast traffic from the device not being seen by the other hosts? The broadcast traffic to the host is being seen, but not the other way around. We don't have broadcast disabled, hence it's working one way.
