<![CDATA[Bandwidth Problem]]>Hi everyone, i have some Issues with my bandwidth. Always full : Graph 1
But the lan output does not match the in from wan. It's like something in my network send a request to the exterior to flood my firewall.
All traffic come from akamai and others cache servers : graph 2

Any ideas ?
