Moving IPs and leaving port 81

If I create a new site in Server Manager using the new IPs, all goes well. The vhosts.conf and the dns are set up properly as far as I can see. I can ping the address, but when I try to get to the website, I get an error:

Firefox - "Firefox can't establish a connection to the server at..."
