Oh, I see. I used ClarkConnect prior to this; that is what got me used to the Firewall/web/Email all-in-one approach I guess. After re-reading the ISPConfig documentation and installing a second time, I began to wonder.
Sounds like I need to re-think the network roles and layout and start again
So is it correct to say that normally you would set ISPConfig behind a firewall and use port forwarding/IP mapping with an internal IP address?
It is a security risk to have it set up with an external IP address (and presumably the web admin page accessed via an external address)?
I am having difficulty now seeing where it would reside on the network.
