it is strange that my one camera consume half of the bandwith of all the 44 net bandwith
Oh but that is only the traffic from tunneled hosts talking to the internet via amprgw! We output about twice that amount (700kB/s) continuoously on our gateway for only network 44.137.0.0/16.
And that is after the Brandmeister hosts have been disconnected for internet addresses due to the DDoS. Before that, it was several MB/s, up to about 8 MB/s last february.
