Hello SteveK and thanks for your welcome.
The redHat installation itself and setting up of the services ( ftp, iptables, apache etc. ) isn't a real problem; I read lots of postings and thanks to them I figured out what and how to do.
My problem resides in external/internal IPs and making the website to be visible from the outside.
Now we have the website on another server and the DNS is according to that. I know that at a moment I will have to change the nameservers to point to our server's IP. What I don't understand is how to give an external IP to the server and the other settings I need to consider in order to have the whole thing up and running.
I don't know how to tell it more clear; my problem is that I cannot say "I don't know something" as long I don't know at least what am I suppose to talk about...
So, supposing that I have the following:
- a server with the OS installed and running 100%;
- a website uploaded on it;
- an Internet provider
what should I do next to make the website visible on the Internet?
Thanks again, very much.
