Configuration:

  • WiFi Router <-> Gateway PC (Ubuntu 11.10) <-> Internet
  • iPad 2 (iOS 5.0.1) <-> WiFi
  • MacBook Pro late 2007 (OS X 10.7.2) <-> WiFi

The WiFi uses static IP configuration, no DHCP.

I can ping iPad IP just fine from both Gateway and MacBook. I can ssh (via iSSH) from iPad to the Gateway just fine. I can ssh and otherwise ping from Gateway to MacBook just fine.

The problem: any connection (including SSH, telnet and trying to open something from Safari) from iPad to MacBook fails by timing out.

To do some debugging I need to be able to connect directly from iPad to my MacBook. Any clues how to troubleshoot my problem?

Both Mac and iPad were connected to the same WiFi access point.

That WiFi access point was working in "Isolated AP mode", that prevented clients from seeing each other.

Doh.
