I had sharepoint 2010 installed on my WHS 2011. I successfuly created a new web application and site collection. I created a new SP default site on a port different from 80 and restarted the WHS 2011 default site in IIS. I could see both the WHS 2011 and SP 2010 default sites from the server, my client PCs, and from my office. Great!
I uninstalled SP Foundations 2010 and installed SP Foundation 2013. I successfully created a web application on the same port I had used for SP Foundations 2010 because the firewall rule on my server and the port forwarding on my router where already in place. I again restarted the WHS 2011 default site in IIS. I can see the WHS 2011 and SP 2013 Foundation default sites from the server and my client computers. However, I can't see the SP Foundation 2013 site from anywhere outsite of my home network.
Help someone?
