I use ipfw on freebsd7.

I have two questions

1- I want to fix an ip address for each mac address. But some pc and servers have more than an ip address. How can I map multiple ip addresses for a mac address?
2- I want to allow these fixed mac addresses using ipfw. After that I want to deny all mac address via the server's local ethernet card.  How can I do these cases?
