My ISP is blocking port 80 so I want to change it to something else. I have looked at the how to by Dan Brown but this doesn't work for this version. Any help would be appreciated.
Thanks. 
Leave the web server listening on port 80. On the port-forwarding panel, forward port 8080 (or whatever) to port 80. In 6.0, the destination IP must be your
ExternalIP. For 7.0, you can enter any of "localhost", ExternalIP, InternalIP, or 127.0.0.1 for such redirects.
