A few moments ago I was trying to open Youtube when the browser (Chrome) notified me that I have no internet connection. All of my cable connections were OK. I disconnected the cable from my computer and reconnected it and the website opened. However, upon inspecting my router log I noticed that it alerted on and blocked a UDP flood from my own IP to an IP belonging to Google at the exact time when the website wouldn't open.
Can someone give more explanation to what actually happened?
I have Symantec EP installed on my computer. I also keep noticing that I have a fair amount of IGMP traffic in the Symantec logs.
Should I block IGMP traffic in my firewall settings?
