Error when forwarding port 80

[Chris Williamson]

I can forward host port 8080 to guest port 8080 without problems. But when I try to forward host 80 to either guest 80 or guest 8080, I get this error:

NAT#0: configuration error: failed to set up redirection of 80 to 10.0.2.15:80. Probably a conflict with existing services or other rules. VBox status code: -3002 (VERR_NAT_REDIR_SETUP).

Result Code: 0x80004005 Component: Console Interface: IConsole {1dea5c4b-0753-4193-b909-22330f64ec45}

As far as I know, there is nothing running on port 80 on my host. I don't have a Web server installed on the host and never have.

I'm using the open source edition with Ubuntu 7.10 host and guest.

This is a known limitation, not of VirtualBox but of Linux: On Linux, only the root user can bind to a port below 1024.
