Disable gateway monitoring actions without disabling gateway monitoring
Mentioned in this thread: http://forum.pfsense.org/index.php/topic,65452.0.html
In sites with single WAN, I still put a realistic gateway monitoring IP (e.g. Google 184.108.40.206) so I can see what the WAN performance is like. By, like the OP in the thread, I don't want apinger/pfSense to take any action at all based on the monitored stats (latency, loss, even member down).
