Guest Donkey Posted July 7, 2012 Posted July 7, 2012 I notcied my firewall was getting ICMP's from 108.162.195.108 So i did backtrace looks like it was from coming from here(LoversLab). Not sure what happened.
Ark of Truth Posted July 7, 2012 Posted July 7, 2012 So i'm not the only one gettings this then. I just bounce them away from my network, I have no idea why we are getting them though.
Symon Posted July 7, 2012 Posted July 7, 2012 Very odd. What type (there are several in use) Echo request (type 8) or something else? http://en.wikipedia.org/wiki/Internet_Control_Message_Protocol
Ashal Posted July 8, 2012 Posted July 8, 2012 CloudFlare sends ICMP requests for security reasons to help prevent DDOS attacks, its just part of how their CDN works, absolutely nothing wrong with it and blocking them is nothing short of paranoia.
Symon Posted July 8, 2012 Posted July 8, 2012 It's a sad fact that people do get paranoid about ICMP. As you say, they shouldn't, it's there for a reason. Blocking 'Destination Unreachable' for example, is a seriously bad idea. Gives you timeouts that can take minutes rather than seconds. Still, even large institutions do it, don't get me started about yesterday. Save me from people who block diagnostics! I blame the 'ping of death' flaw that used to exist in Microsoft's tcp/ip stack.
