Question regarding DMZ zone on cisco FW

Asked by: sahil-sabir

Hi,
I have a cisco ASA 5510 FW and it is configured with inside and outside network internet. We have a web server (public) and corrently it is on inside segment which i need to move to DMZ zone so i have created the DMZ interface and moved my web server to DMZ zone and from DMZ zone i am able to access all my application server which is inside by using DMZ NAT IP addresses. some application reasons i need to access from my web server to internal servers using real IP address (with out NAT) so is it possible to do that and how can I do it. I have tried a lot but it is not working. as a test i allowed (tcp, udp, ip) any any traffic to inside interface as well as the DMZ interface but still it is not working.

The server (DMZ) ip is nated with public IP.
From outside I am able access web server
From web server I am able to access the inside application servers if I am nating and using the NAT IP address
From web server I am unable to access inside server if I am using the real IP (real IP and DMZ nat removed)
