Hi aradke,
Thanks for the post.
My setup is OPSi with wifi, as mentioned router is the AirPort Extreme (AE).
Using the Airport Utility via my iMac I have successfully set up port forwarding for another device and was able to verify it was open using http://www.canyouseeme.org. The difference is the device is connected to the Airport Extreme via ethernet connection.
I am try to do the same thing with the RPi using its wifi connection to the AE. Using the Airport Utilty I am able to add the RPi, its IP address, mac addr, and port number using the same method I set up the other device (that’s port can be seen as -open- on canyouseeme.org.
At this point I can’t see the RPi on canyouseeme.org even after I changing it to port 80 and the other device to 81. (I can see the other device on canyouseeme.org under port 81)
Think I am pretty close to success, but need a few more clues.
Thanks,
Kevin
