Cisco 7204 - Allowing Access Only to DHCP Clients

I have a Cisco 7204 router here that has a couple different bridge groups of DSL connections. One bridge group has a dedicated class C for static IP addresses. The second is set up using DHCP to assign dynamic IPs to clients in the group. We are having a problem with people in this group statically assigning IP addresses to their computers, probably so they can host servers. Is there any way to instruct the router not to bridge traffic for users who are not in the DHCP bindings list?

Also, another DHCP question. It seems that once a particular user gets an IP address from the router once, they end up getting the same address each time after that. We would like the router to give it more of a random IP, to keep people from running incoming servers, etc. Is there any way to force the 7204 to give it a more random IP address? Any help anyone could give me on these would be great. Thanks.
