You can always copy all incoming traffic to a local sniffer segment, and
place your sniffer equipment on that segment. Tapping traffic in the
router slows down the router. Tappers usually wish to keep the tapping
secret. Naturally, you can use a special hardware card to do the tapping
for you. Expensive, though.
