Old WNR2000v2/3 - possible to monitor traffic?

Hi,

As the title states. I'd like to monitor and block traffic on my ancient WNR2000v2 or WNR2000v3 (I haev both) Netgear wireless routers. The blocking works, and I've selected to log any attempts both successful and blocked, but nothing is logged (other than DHCP responses and logins to the admin UI, and some portscan attempts). Traffic from inside the network to either another node inside, or to the outside, is not logged.

Anyone know if this is by design, or if there's something I can do to fix it? I have installed the latest available firmware on both devices.
