If you see a 'getIGDPortmaps' alert in OS X Server
Use these terminal commands if you see messages that mention "IGD" when you try to administer an AirPort device.
If you've upgraded from an earlier version of OS X Server, you might see an alert message in Server.app when you try to configure an AirPort device:
"An error occurred on the server while processing a command. The error occurred while processing a command of type 'getIGDPortmaps' in plug-in 'servermgr_network'".
You might also see repeated messages in the system log like this:
servermgrd[2594]: Failed to connect to the IGD, no status info available, error is Error Domain=com.apple.ACPDevice Code=-6753 "The operation couldn't be completed. (com.apple.ACPDevice error -6753.)"
If this alert message prevents you from administering your AirPort device from Server.app, use the following terminal commands:
sudo /usr/libexec/PlistBuddy -c "delete :managedIGD" /Library/Server/Network/Config/autoportmap.plist
sudo /usr/libexec/PlistBuddy -c "delete :lastIGD" /Library/Server/Network/Config/autoportmap.plist
After entering the commands, these messages should no longer appear.
