I Have a little Problem with a my Astaro SG120 (V5.x)
I can see traffic peaks on the external interface (eth1) that come repeatedly every full hour and last for about 20 Minutes. Thhis traffic takes almost all of the available bandwith and i have no idea what it is. i have a daily traffic volume of abou 5GB a day where i had about 500MB before. I am not able to trace what kind of traffic it is and where it comes from.
The only ports i have opened are 80/443 for a webserver and 25 for Mail. But this is not the cause of the traffic. Otherwise i would see something in the packetfilter logs i guess...
Could anybody give me a hint how i could find out where this traffic comes from? Any help and ideas would be appreciated...
