Cisco ASA NAT CLARIFICATION

Dear Experts,

I am wondering if i need to have NAT statements in my ASA even
when i am not connecting to the internet.
My setup is such that remote offices need to access a server located
on the dmz at the headquarters.
Assuming the server on the dmz is 172.19.30.17/32 and my LAN
network (sitting on the Inside interface) is 172.100.1.0/24, while my
outside interface is 192.168.7.1 (this connects to a private WAN
), do i still have to have NAT traffic from inside to outside as is the
case when connecting to the internet? how about traffice from
inside to dmz? and vice versa?
My understanding of the nat (inside) 1 172.100.1.0
and global (outside) 1 interface is that they are used for natting when
connecting to the internet. What statements do i need to have in the
ASA since this time around, i am not connecting to the internet?
Also, what will my static (inside, outside) statement look like to be
able to access the server in the dmz from the remote offices?
Thanks in advance for your help.

I can barely understand what your problem is but if dmz port has it's own ip and then the server on the dmz has a nother ip totally different you need nat.

If your dmz port ip and server ip is same and you have correct routing dmz server should be able to get internet connection excep if this is not a resource for public like web server etc. then you need a nat from outside to inside only for dmz port.

as I said if you have correct routing when you type the ip of the dmz server from inside you can get to dmz server with no nat.

but if it's a domain name then 1st case must be completed. because they will have to go to internet and then directed to your server.

you have nat enabled for the inside subnet. you need to have something similar when the traffic goes between inside and dmz.
