Hello all,
I detected a strange (for me) behavior of my external connection: usually I have 10-20 concurent connections (all PCs behind astaro are off), but when i start one computer in my lan and go online, directly I get 300-400 concurrent connections (I see it under "Reporting"-->"network usage"). I checked all my computers with antivirus scanner without success, no virus detected and I am very careful concerning installing new software, I think my computers are all clean. And I got so many concurrent connection too if I go online with another computer. Sometimes I see on the dashboard on my external interface incoming traffic of nearly 6Mbit (I have 6000Mbit DSl), but only on external interface, not on internal_lan or interna_dmz interface, thats strange. When I open the pppoe logging I see lines with Bad TCP checksum *** and the intrusion prevention logging show me "ICMP flood detected". Is that an really attack on my network?
Have anybody an idea why i get so many concurrent connection when I go online?
Thanks in advance, matti.
