Basic natting ( or no natting) question

I have a 515 running 6.3.3 with a DMZ. I am having some problems understanding the natting for the DMZ. Basically I have an internal network (10.0.0.0/8), DMZ (172.18.5.0/24), and outside (0.0.0.0/0)

I would like a DMZ server to be able to address the internal server with the 10.0.0.0 address without a nat. Basically I would like the DMZ to know the real addresses of the inside, and the inside to know about the real addresses of the outside. I would also still be needing to keep the dmz servers statically natted to the outside of course. Am I missing something, or do I just need two nat 0 statements? After that I should just be able to create ACLs for lower security interfaces to get to higher...

I am still getting the no translation messages...

Re: Basic natting ( or no natting) question

I think it should be something like the following.

static (inside,dmz) 172.18.5.0 172.18.5.0 netmask 255.255.255.0

Re: Basic natting ( or no natting) question

Use the static command to translate the dmz and inside address to itself. Leave your static for the dmz to outside.

static (internal-interface, external) global-ip local-ip netmask MASK

static (dmz, inside) 172.18.5.0 172.18.5.0 netmask 255.255.255.0

static (inside, dmz) 10.0.0.0 10.0.0.0 netmask 255.0.0.0

Thanks,

Chad
