How do I determine why occasionally I lose internet connection for just a brief moment a few times a day since putting this pfsense box up, no issues at all with my connection before the pfserver. What should I look into to see if anythings shows up anywhere? I assume logs, but which logs, how? what am I looking for?
Determine if apinger is detecting and marking the interface down.
Maybe try increasing the apinger down threshold. Or disable apinger to see if that helps.
