I believe that the listening device has to be on the subnet that it
wants to listen to. Sniffer can snoop all packets that come accross the
subnet, even filter on specific contents. However, not accross subnets.

You can use something like HP-LanProbe with a probe on your important
subnets. Then from the management console you can collect packets
and review them remotely.

One thing I hate about sniffer or expert sniffer, you can only filter
on say four ip addresses. Example say I had ten w/s and I wanted to
so how much bandwidth they were taking, I could not do. Sniffer limits
you to four 4,3,2,1, or all.

Good Luck,

Andy
