Network topography: Internet === Verizon DSL Modem === Time Capsule Router === Mac Mini web server
I go to icanhazip.com and grab my public IP address. I throw it into a web browser and get...my Modem's admin interface. I didn't expect that. I spent an hour but was unable to get any further.
My configuration: The Verizon DSL Modem's firewall is totally disabled. The Time Capsule is setup to forward traffic on port 80 to the Mac Mini (it's default web server is enabled).
I briefly hosted my own website on my desktop PC back in 2002 but I've never been great with networking. I don't want great performance. I just want to do this for the educational benefit and geeky thrill. And I want a sandbox where I can put my programming and design experiments.
What am I missing? I expected to see the router's admin screen when I hit its internal IP address but I am surprised (and a tiny bit frightened) that I see its admin screen from its external IP address. Should I setup a DMZ (do I give it the router's outward-facing IP?)?
