I am using Telocity/DirecTV DSL, with static IP via dhcp client. My dhcp client attempts to overwrite /etc/resolv.conf, removing my private nameserver entry - this prevents the firewall machine from resolving local LAN addresses. My firewall is Debian unstable, and attempts to change resolv.conf when the initial negotiation occurs. I see an option in dhclient.conf to "prepend domain-name-servers aaa.bbb.ccc.ddd", but have not tried that yet - I edited resolv.conf and set the immutable bit for now.
