Your IP at the time was this:
$ host cmb8-158.dial-up.arnes.si
cmb8-158.dial-up.arnes.si has address 194.249.38.158
DNS suggests it's a dialup node, but it's on your eth0 interface? If
it's Ethernet, 194.249.38.255 might be the broadcast address.

The origin ports seem to be incrementing, whilst the destination port is
fixed. Were you doing some kind of port scan?

Oh well, enough of this for today. You can't make a post like this and
expect to get much useful information, because you gave us nothing to
work with.

This packets are logged on my external interface. Im on cable, and IP
address starts with 82.xxx.xxx.xxx. I have nothing to do with this
packets. They are just logged.

NO this is NOT my ip address..

Yes, its on external Ethernet card. If 194.249.38.255 is broadcast,
why then they end on my inetcard, which is on completly different network,
ip.

Is this kind of DoS or something.. constantly flooding my external
interface with UDP packages... Definetly they all end on 39213 port, and
source port is incrementing.., BUT source addres is on different network
than my addres and destination addres is also on different network... so
why they end on my interface??? This is going on for days... making me
little nervous...

Quite likely its something simple like a broken router misdirecting
packets to you. As to why its only *from* that address I don't know.

It would certainly seem to be broken "routing" for sure, and the break
is not too far away. It may have started "far away", but somehow it
is propogating to you -- from your ISP! I would contact them to see
what's going on.

In the meantime, for your amusement I tried this from a quick-n-dirty
whois on the source:
http://www.whoisd.com/google-alexa.p...arnes.si&GO=GO
and somewhat more info:

A ps followup to previous post -- I couldn't resist.
global Google search:
"udp port 39213" << with quotes
first hit leads to:
http://cert.uni-stuttgart.de/archive.../msg00266.html
which leads to:
http://www.google.com/search?q=Sygat...UTF-8&oe=UTF-8

Could it be your next door neighbor?

That would be in accord with what I found on some of the Alexa usage
stats pages -- a few were in English. In fact, I was rather surprised
just how widespread a "presence" they have. And some of the Google
pages showed concerns/traffic similar to yours, but consensus seems to
have been that it was normal/harmless.
