Got dd-wrt setup!

Can I log urls visited on all computers on the network?

You can actually use the following firewall rules on the dd-wrt firmware to force users to use a specified DNS server (in the router settings)

iptables -t nat -A PREROUTING -p udp -i br0 --dport 53 -j DNAT --to $(nvram get lan_ipaddr)
iptables -t nat -A PREROUTING -p tcp -i br0 --dport 53 -j DNAT --to $(nvram get lan_ipaddr)

This was supposed to be a comment to the answer posted by jason404 but I can't because of my low rep :)

This feature is not currently available in the DD-WRT firmware.
