Hello all. I would like to preface this post by saying I am very new to firewall configuration. I have a PIX 515E O/S version 7.0(2). I am trying to implement a most basic configuration in a test
environment. My goal is to have our webservers in the DMZ with access to them from the inside and outside interface.
From the inside network in our test environment I am able to access internet sites via ip address, but DNS is not working. Also, from the inside network I am unable to reach internet ip addresses of the
webservers in our current production DMZ. Could this be a subneting issue? We own 12x.17x.24x.128-161. We use 12x.17x.24x.128-144 in our production environment. Our test environment uses
12x.17x.24x.145-161.
Secondly I have configured a webserver in the test DMZ. At this point I have been unable to contact the lone DMZ webserver from either the inside or outside interface.
I know the current firewall configuration is wide open. It will be required to be more restrictive once in production. I have just been trying to communicate with anything at this point.
Any help is appreciated! I have pasted the config below. Thank you in advance.
