ASA 5510 DMZ configuration

I currently have an ASA 5510 with which I'm trying to setup a HTTP/FTP host on a dmz. Currently the DMZ host is accessible externally but hosts on the internal network cannot access it. I have a dedicated IP for the DMZ host (1.1.1.228) and another IP for interface PAT for the internal clients (1.1.1.238). I know I'm missing a piece, either a nat() statement or a static() statement, please advise.

interface Ethernet0/0

description Outside Interface

nameif outside

security-level 0

ip address 1.1.1.238 255.255.255.240

!

interface Ethernet0/1

description Inside Interface

nameif inside

security-level 100

ip address 10.0.0.1 255.255.0.0

!

interface Ethernet0/2

description DMZ Interface

nameif dmz

security-level 50

ip address 192.168.0.1 255.255.255.0

Add:

static (inside,dmz) 10.0.0.0 10.0.0.0 netmask 255.255.0.0

The above statement will allow the Inside host to access DMZ hosts using DMZ devices own IPs, and vice-versa.

And if necessary, use ACL to restrict access from inside to DMZ, or DMZ to inside.

Cheers!
