A better idea would be to run a caching nameserver on your FreeBSD
machine. If you run a traditional caching nameserver, you won't
need to worry about the nameserver passed to you by the cable modem
connection.
If you want to modify the caching server to use the cable modem
server as the 'upstream' connection, your cable modem DHCP client
script would need to edit named.boot to edit the address you've
just received into the 'forwarders' line, then (re)start the named
server.
In both cases, your dhcp server should advertise your FreeBSD
machine as the DNS server to your clients.
