I have a web server sitting on the dmz. I added a global statement which I understand allows all inside clients start connections to the dmz and outside interfaces. I can access outside resouces but I am unable to access the web server on the dmz. What I'm I missing.
You have to statically assign a public IP address corresponding with the private IP address used by your Web server with the command "static".
You have to create an access-list to open a port to your Web server and finally assigned the access list created before to an access-group assign to the outside port. You can see an example at the following URL:
Since you are trying to access a web sever from the inside, which is the highest security interface, all you need is to crate a global (perimeter) entry. But youhave to make sure that there is a nat entry for the inside network. The nat id for the nat (inside) entry should match the id for the global (perimeter) entry. For example if you have nat (inside)1 10.0.0.0 255.255.255.0, then you should have global (perimeter) 1 172.16.10.0 255.255.255.0. Users on the inside network would use 172.16.10.0 net to connect to your web server. You don't need any conduit statement since by default the pix allows all connections from the higher security interface to any lower security intf. If you want your web server to initiate a connection to the inside network you will need the static command. I think you've been doing the right thing all along. You need to make sure that the nat id matches the global id.
