Hmm... I had no records in System > Server IP addresses. I've only one IP for my server. It in System > Server Config >Server > IP Address. But there is no deafult port on System > Server Config > Web page.
I tryed create new record for the same IP address and port 82 on System > System IP page and set the IP on Sites -> Websites page, but nothing to change and my site answer at port 80.
