Setting up ssh/http port mapping on a Mac using Airport (Extreme)

1. Find your computer's MAC address
   • Airport utility
   • Advanced section
   • Logging & statistics tab
   • Click on "Logs & statistics" button
   • DHCP clients section
2. Ensure that DHCP IP address stays the same.
   • Airport utility
   • Internet section
   • DHCP
   • Add a DHCP reservation
     • Description: e.g., Norple@10.0.1.2
     • Reserve by MAC (not client—it's not working for me)
     • I used 10.0.1.2, a fine IP address indeed
3. Set up port services
   • Airport utility
   • Advanced
   • Port Mapping
   • Add:
     1. SSH (choose nonstandard public port, like 2319, private can be 22)
     2. Person web sharing
     3. Others...?
4. Update Airport so that it shuts down and restarts
5. Set up web and file sharing on your computer
   • System preferences
   • Sharing
   • Check remote login, web sharing, whatever you want.
