Yes, ISP's have some interesting routing tricks they do.  For instance, at home on my cable modem, all traffic is routed through a IP address.  I've also noticed occasional connection attempts from similar IPs.

I find this interesting since on my traceroutes there is no indication that I even have a firewall between myself and the cable modem.  As I understand it, from my home machine, my firewall should be the first hop on ANY traceroute.  

I think I even made posts to this list about it when I first noticed that was going on.  Fortunately, another person said they had seen that trick on their cable ISP.

And for my $0.02 on Kornet...  I find it very hard to believe that the IT people at Kornet aren't required to know english.  I've never worked internationally, but I was under the impression that if you worked on PCs anywhere, you had to know at least a little english.  Sure you can run windows in a number of language modes, but that doesn't mean that all software supports it.  

Has anyone seen a router that can be configured in Korean?

     Port 137 UDP could be either TROJ_MSINIT.A (see 
     INIT.A) or NETBIOS Name Service. 
     Since it's coming from a 10.X.X.X address, would it be safe to assume 
     that Keith's ISP probably has a machine with that address that is 
     sending the queries?

I received two Port 137 UDP attacks from addresses within the 10.x.x.x 
block. I am a home user and am not very knowledgable about the reasons for 
Reserved Addresses. Is there any way of finding out where they have come 
from, and who if anyone to report this abuse to.
