Redirection to a Private network address on a firewall

Hi All If you set-up a DMZ with a private network address. Is it possible to configure IPCHAINS to redirect SQL server client requests & HTTP requests from the Internet to a Server sitting in the DMZ with a private network address. Internet ------Legal IP Address----|-----------Internal Private Network 10.x.x.x | | DMZ Private Network 192.168.x.x Thanks in advance Steven
