I am on a 2010 Macbook Air connected to the web over wifi tethering on my Sprint Nexus S.
I want to be able to host a few files using MAMP, but it seems that Sprint is running a NAT. When I query checkip.dyndns.org right now, it returns 68.27.228.75.
However, trying to navigate to that IP fails (even though I do have MAMP's Apache running on port 80, as verified via loopback).
When I whois 68.27.228.75, it appears to be a Sprint address, with NetName "SPRINTPCS" and OrgName "Sprint Nextel Corporation".
So, is there some way I can circumvent Sprint's NAT to allow people to connect to my server that is running on a Nexus S Portable Wi-Fi hotspot?
