How do you set up shared hosting?

[PorkFat]

I've had a site running on port 8086 with port forwarding on my linksys router because my ISP blocks port 80 incoming to it's customers.

Well, I set up ISPConfig to operate on port 80 internal, but when I log onto port 80 on my server's 192.168.xxx.xxx IP address, I get this:

Shared IP

This IP address is shared. For access to the web site which you look for, enter its address instead of its IP.

For questions or problems please contact the server administrator.

If I log into port 8086, I get my original site just fine. How do I get port 80 to display my /var/www/web5/web/index.html ? How do I make that shared IP message go away?

Thank you so very much for your help!
