you mean, a new box inside your network acting as dhcpd server?

My topology is equal to yours.
Your FreeBSD box --the firewall above-- can be used as DHCP server.
You don't need another computer doing the job inside your network.
Perhaps this can help you:


---------/usr/local/etc/dhcpd.conf-----------
 ddns-update-style none;
 subnet 192.168.1.0 netmask 255.255.255.0 {
         option domain-name-servers your_name_server_ip;
         option domain-name "your_domain_name";
         range 192.168.1.2 192.168.1.50;
         option routers 192.168.1.1;
         option broadcast-address 192.168.1.255;
         default-lease-time 600;
         max-lease-time 7200;
 }
---------------------------------------------

just change your_name_server_ip and your_domain_name, accordingly.
