programming to tell it to forward the packets. Even if I dug through the
source (which is available on the Linksys site!), I couldn't change the code in
the router.
It has a Port Forwarding feature, but I think that's only to forward specific
ports from the outside (internet) to an IP on the LAN. I could tell it to forward
port 80 traffic to my PC, but I think that would only forward incoming port-80
requests from outside, not the port-80 traffic from my son's laptop.

What about computers that are connected directly to the WRT's ports, with
no switches in the way? Would they see the packets, or would the WRT still
not forward the packets to those ports because they aren't the target of the
packets?
If none of those tricks work, then I guess the only way to do this is to run
Wireshark on my son's laptop. Not the greatest solution. Ohwell....
Thanks,
