Access list on an ASA firewall

Got a slight problem and wondered if any of you may be able to help
 The scenario :

Have a server IP address 192.168.200.16 its default gateway is 192.168.201.254 (which goes out on the internet) there is another route which goes to another firewall which links to some servers on a DMZ. this DMZ firewall ip address is 192.168.201.253.

I have created a static route on this server to go to this DMZ firewall;
192.168.12.0 255.255.255.0 192.168.201.253
10.0.0.0 255.255.255.0 192.168.201.253

I have also created another static route on the server on the Inside interface too.

On the DMZ firewall there are 2 interfaces
1: Inside 10.0.0.254
2: DMZ   192.168.12.100
3: Outside 192.168.201.253

I have a computer on the Inside interface 10.0.0.51

I want the computer on the inside interface to talk to the computer on the outside interface.  The outside interface already can speak to the computers on the DMZ interface, but for some reason can not speak to the computer on the inside interface

Any guidance will be much appreciated

thanks

here is a snippet of the code:

Is the 10.0.0.0 network a /8 or a /24?  It's referenced as both, a /8 in the interface, and /24 in the ACL.  If it's a 255.255.255.0 subnetmask you should adjust your interface mask.

int g0/1
ip address 10.0.0.254 255.255.255.0

As for the problem you're having, the traffic coming from the Inside network is being NATed to the outside interface IP.  To eliminate this:

access-list nonat-inside permit ip 10.0.0.0 255.255.255.0 192.168.200.0 255.255.254.0
nat (inside) 0 access-list nonat-inside

Hi gavving

firstly thank you for your quick response

I changed int g0/1 to a /24

i also added the two below lines:
access-list nonat-inside permit ip 10.0.0.0 255.255.255.0 192.168.200.0 255.255.254.0
nat (inside) 0 access-list nonat-inside

but i am still unable to ping between the networks.

I have tested each server and each server can ping its own firewall interface but unable to cross over to the other network

many thank
