Unless you are using proxy-ARP, you need to:

a) configure the routing tables on the DMZ hosts to use the firewall
as the gateway to the Internet (and the external router, if you need
to talk to it), and

b) configure the routing table on the external router to use the
firewall as the gateway to the DMZ hosts.

You may wish to use "sysctl -w net.ipv4.conf.all.proxy_arp=1" to
enable "automatic" proxy-ARP on both interfaces.
