Hello. last week i had some problems because there was a user or users i dont know why that was filling my 12 users licence lines instead of the users of my domain that are always from the range 10.81.8.111 my proxy that wasted gigabytes of my traffic (in portugal we only have 4 gb international...shame..).
I really dont know where this users come from...i trace them to several countries...china, japan, framce, etc.
What i do is to disable user guest but now with this ip.82.154.164.36 its trying to enter every 2 minutes.
Question: does this affect perfomance...always trying to enter?
Can i block this specific range of ips or just ONLY alow ips 10.81.8.etc?
this 82...ip i think is portugal ip...is it caused by the router? a thompson 510 router?
thanks very much.
