It actually depends on what services you want from the ISP.
Most people configure their ISPs to provide web, DNS and FTP services.
In this case the ISP requires:
1. ISP Router
2. Web server
3. DNS server
4. FTP server
Since packet tracer doesn't yet support FTP, the first three will do.
Configure the DNS server with the domain names and addresses you want it to translate and assign your hosts DNS-server ip.
Cofigure the Web server's HTML in any way that dims fit to you. You can have as many web servers as you want, provided you specify them in the DNS-server configuration.
In packet tracer, use the select tool and select all the equipment you want to be at the ISP. Click on the New Cluster tab.
You now have your customized cloud acting as an ISP.
I hope this helps.
