Humphrey, what kind of packets are they? Is it possible somebody from
those addresses is recieving some kind of data from your LAN?
Possibly unauthorized data? Is it possible those are forged packets?
Can you trap a bunch of them to check? I would think it highly unlikely
that the cisco hub or routers are causing this.
Perhaps put a packet sniffer on the LAN?
