I've successfully completed this tutorial: http://www.instructables.com/id/Web-Con ... y-Pi-GPIO/ titled "Web Control of Raspberry Pi GPIO (UPDATED)"
Everything appears to be functioning correctly. I can log into the pi locally at 192.xxx.xxx.27/control.php and toggle the IO.
I don't have much web server experience beyond a yahoo domain that points to an index.html. How do I make that page accessible over the internet? I have a dyndns domain that I use for other purposes (typically in the format of xxxx.dyndns.org:4949) I don't want to loose this functionality. Is there a way to point a specific port to the .../control.php file on my Pi? What security issues should I be concerned about?
TIA for any advice.
