I’ll try to make it more clear, sorry.
local_domain.com: il mio hostname in locale (intranet, home server linux which I’m setting up)
http://my_server.no-ip.com:xxx: no-ip.com offer a free dynamic DNS name like dyn.com or openDNS.com. This is the address of my private webserver from outside the intranet, remote access
virtual_host: this will be the name of the forum or cloud as specified in the virtual_hosts file of apache
in other terms, if:
forum.no-ip.com is the dynamic dns name provided by no-ip.com
8100 port to forward to my webserver (intranet, home webserver)
forum is the web site as installed using virtual_hosts in apache2
to access the forum from outside the intranet I’ll write on the browser addtress:
forum.no-ip.com:8100/forum
http://…: I need to verify if the free service allow an https connection (make it sense as question?!)
