pfBlockerNG not blocking
I specified that all EU IP addresses should be blocked. Then I ran my Firefox browser with the Ghostery browser Addon enabled. Ntopng shows that Ghostery is still connecting to Europe IP addresses. Why is it allowing that? Shouldn't it block all EU ip-based connections?
Check the IPs with this shell command to see what MaxMind is listing as the GeoIP ISOcode (Change the x.x.x.x - to the IP your looking at):
You also need to ensure that you have the blocking rules on the appropriate outbound Interfaces.
