hmm analyzing the log
take a look at these rows:
DROPPED IN=ppp0 OUT= MAC= SRC=188.8.131.52 DST=184.108.40.206 LEN=40 TOS=0x00 PREC=0x00 TTL=245 ID=64926 PROTO=TCP SPT=80 DPT=1037 SEQ=2538350621 ACK=4238546219 WINDOW=9300 RES=0x00 RST URGP=0
this means there's an incoming packet from 220.127.116.11 (this seems to be google), the source port is 80 (http) wich is the web server port (looks allright). the destination IP is 18.104.22.168, wich must be yours. the protocol is TCP ofcourse
blablabla etc anyway, it's nothing to worry about, exept for the fact this shouldn't be in your dmesg output (as far as I know). how this is possible I don't know...

ps: nothing wrong, exept the packet is dropped
you don't use the internet on that machine? or: can you use it?
