Networks managed by Simple Network Management Protocol (SNMP) may be vulnerable to “denial-of-service” attacks. (SNMP is turned on by default in AirPort Utility.) Similarly, if you allow your base station to be configured remotely over the wide area network (WAN) port, unauthorized users may be able to change your network settings.
To help protect your network and wireless devices, turn off SNMP.
Open AirPort Utility, located in the Utilities folder in the Applications folder on a computer using Mac OS X, and in Start > All Programs > AirPort on a Windows computer.
Select the device you’re setting up, and then click Manual Setup. Enter the password if necessary.
Click Advanced in the toolbar, and then click Logging & Statistics.
Deselect the Allow SNMP Access checkbox.
You can choose to allow SNMP on the wide area network (WAN) port by selecting the “Allow SNMP over WAN checkbox.” Allowing SNMP over the WAN port lets you manage your devices remotely.
Click “Logging wireless network information” below for information about setting up the wireless device to log network information.
