The company is extremely concerned with security. There is a lot of sensitive data on the servers and this is understandable. What I struggle with is getting many of the addons to operate properly, as well as some core functionality due to this setup. I have no control over the setup so I need to try and figure a way of configuring EE to comply.
The setup is as follows:
Admin is contained on a sub-domain of the primary site and sits behind a firewall. So an example would be something like CP Access and System files are at http://admin.eesite.com and the public site is at http://www.eesite.com
The public site is open to the world. The admin is behind a firewall in which you must be connected to the internal network before you have access.
Most things function as they should, but this has proven to be an extremely problematic setup for using add-ons, and tiresome for performing updates, etc. because it is an MSM install and each leg of the site has this same setting for each segment.
Most of the problem I run into are 403 or standard 500 errors. Everything is hosted on windows servers via IIS7.
I am running EE 2.7.2
