We are trying to decide if we need to use iChain or not, and we need some information. We currently have a BM 3.8 server running, it does the basics Firewall, Packet Filtering, etc. However we are looking at hosting multiple web sites, and allowing more outside access to our network, and we were looking at iChain because of the security it brings.
First)
Is there a detailed sheet that shows a picture of how BM and iChain work together? Basically where each would sit in the network?

Second)
I have downloaded iChain admin guide but really can't see in there how it works with BM. Can iChain be used on it's own without BM?

Third)
We have a DMZ zone (that at the moment isn't as secure as we would like it to be) that has to be changed and we want to setup an actual secure DMZ zone(very limited access), and again some of the pictures have shown the iChain server outside of the firewall, and others have mentioned using iChain inside of the firewall. Is there documentation that can help direct us on how to fully setup the DMZ zone, and how to place the iChain server, and BM?

Thank you for all your help in this matter, if you need any further information please let me know.
