I have ISPconfig installed on a Fedora Core 6 system. I'm behind nat router (firewall) and I have made a rule that port 80 is forwarded to this server. I have now only one IP address from my ADSL. I will register a domainname that point to my WAN IP. Now is my question. How does this server with ISPconfig know wich website he must give (I like to use only subdomains on it.) And How must i set the DNS in ISPconfig??
