I am using the latest Astaro softwareversion (home license in order to get to know our commercial version in the office better) and try to avoid setting up too many firewall rules.
So last time I was having a closer look into the logs I came over some strange entries which I am not able to identify - help would be appreciated.
I have a wireless lan with some Android phones on it and one phone (I can specifically determine which one via mac-adress) is creating strange firewall-logentries.
My WLAN-network is something like 192.168.1.0 and what I normally see in the logs is something like this:
2012:05:03-07:37:57 action="accept" srcmac="0:24:..." dstmac="...6:64" srcip="192.168.1.69" dstip="193.45.15.98" proto="6" length="40" tos="0x00" prec="0x00" ttl="63" srcport="56166" dstport="443" tcpflags="RST"
I can either say that source or destinationIP is within my local network.
But from time to time I see entries like that (from this Android phone):
2012:05:03-07:36:22 action="accept" srcmac="f8:7b:..." dstmac="...6:5a" srcip="10.155.223.24" dstip="173.194.70.188" proto="6" length="75" tos="0x00" prec="0x00" ttl="63" srcport="43674" dstport="5228" tcpflags="ACK PSH"
2012:05:03-07:36:22 action="accept" srcmac="f8:7b:..." dstmac="...6:5a" srcip="10.155.223.24" dstip="173.194.70.188" proto="6" length="52" tos="0x00" prec="0x00" ttl="63" srcport="43674" dstport="5228" tcpflags="ACK FIN"
Code 5228 is apparently some port of the Android Market - which is not suspicious to me. What makes me curious is the source IP "10.155.223.24". The destinationIP 173.194.70.188 belongs to google, according to a quick "googling" ;-) but the 10.155.223.24 is nothing I know within my local network thus strange to me that I can see it in the logfile.
It might be that my knowledge of firewalling is not good enough, but I am a bit concerned right now why this strange IP is showing up. Can anyone give me a hint why this entry is showing up in my logfiles?
Probably something easy, hopefully ;-)
Thanks in advance!
