I have a client who we just put a new DMZ card in for on a 515. Moved a machine out to the DMZ and that server can be accessed from the outside no problem (web server). The problem is, that there is no access from the LAN to the DMZ. I have compared the config to other working configs and everything looks like it should be fine. I am thinking that I am missing something simple. Below is most of the config and everything related to the DMZ. Any ideas on why we can't access the DMZ from the Inside inderface? No ping, no nothing at this point. We just want to allow all traffic from the LAN (inside) to the DMZ. Thanks!

Hello Chad,
Heres a configuration example of 3 interface PIX, running PIX IOS 6.2 Sorry no time for a full explanation but if you require one then you can e-mail me direct on the above e-mail address.
Pix(config)# global (outside) 1 200.200.200.10-200.200.200.253 netmask 255.255.255.0
Pix(config)# nat (inside) 1 0 0
Pix(config)# nat (dmz) 1 0 0
Pix(config)# static (dmz,outside) 200.200.200.1 192.168.5.5
Pix(config)# static (inside,dmz) 192.168.5.0 192.168.5.0 netmask 255.255.255.0
Pix(config)# access-list no_nat permit ip 192.168.2.0 255.255.255.0 192.168.5.0 255.255.255.0
Pix(config)# access-list no_nat permit ip 192.168.3.0 255.255.255.0 192.168.5.0 255.255.255.0
Pix(config)# nat (inside) 0 access-list no_nat
Pls. Remember the rule: From Interface Inside to Interface DMZ requires nat/global command.And DMZ to Inside requires static/conduit. Pls. issue cmd: 'clear xlate' after configuration has been saved with cmd: 'wr m' (write memory)
Hope this helps out for your problem. Let me know how you get on.

Here's the command you must add:
global (dmz) 1 interface
This way, inside hosts will be Natted, based on nat (inside) 1 0.0.0.0 0.0.0.0, to the DMZ interface's IP address as specified with the global command.
Regards,
Ben
