Google DNS 18.104.22.168, 22.214.171.124 auto-blocked
Any idea why Google DNS servers
would show up on the Blocked Sites list?
Triggering source is device, Reason is Port scan attack.
I discovered this after complaints about slow web browsing. I started monitoring while these IP addresses were blocked but I couldn't see any traffic coming from these IPs. Oddly, the expiration timer kept resetting to 20 min after a few seconds, indicating there was new traffic triggering the auto-block.
I ended up manually deleting and they haven't shown back up yet.
