...it's a Linksys WRT54G, no NAT or ARP tables from what I can see. Just a DHCP table and a routing table. The DHCP table lists only the LAN's ip's and the MAC's, and the routing table gives me WAN ip's. I respectively disagree with you on ping times on the LAN. They're very indicative of how busy a particular machine is. Crude, but effective.
